Try out a new captcha system
I built a new version of the captcha challenge-response designed to stop spammers, with a twist appropriate to Greater Greater Washington: it asks you questions about the Metro map.
Spammers have been more and more successful at breaking through the reCaptcha system, even though the puzzles have been getting so hard some real humans have trouble. Maybe this one will not be so easy, or at least they won't bother writing custom code to crack it just for us. Here's an example:
Help me find bugs by giving it a try. A live one will appear below, in the comment area for just this post, for now. The live captcha will appear once you click into the comment form. You can also make it appear on any other post by adding /format/mapcaptcha to the end of the URL for that post.
I might try to add additional types of questions or more maps with other information about the Washington region as well; give your suggestions!

When I make it sitewide, that won't be a problem. I don't think there should be any particular difficulty making these captchas appear on mobile too.

Corey: It will work even if you leave off the part after the hyphen, as well as subtitles or any other crud.
Tim: I'm sure someone could. OTOH, they seem to have managed to do it with the big captcha systems also. I'm figuring they won't bother to put a lot of effort into cracking mine.

2. Unlike, say, the T in Boston, we don't use "inbound" and "outbound" as official public train identifiers, so if that's going to be the system, maybe you should stick to stations for which the answer is very clear. For example, it asked me what the next stop is if you're heading outbound from Mt. Vernon Square. I seriously had to stop and think about this, since I am a daily yellow line commuter and my train's final destination is always Mt. Vernon Square...so the only destination from Mt. Vernon Square is Gallery Place. I know that in/out are defined relative to Metro Center and Gallery Place, so I should be able to figure out the answer. I just had to pause, and the frustration of not knowing or being able to figure out the answer immediately is Captcha's biggest flaw.

I answered "National Airport," but the captcha says that I'm wrong! j/k
Awesome work! FYI, the larger map sometimes doesn't work when I click on the Captcha. I got a 404 message the first time. I refreshed the page a few times. It worked some times, and I got a 404 error some other times. May just be me, though.

On the 404s, yeah, if it was showing the west or south sides of the system the big link wouldn't work. I've fixed that.
As for National Airport, I've set up a special case there so that National Airport will be a valid answer when that station comes up. I wanted to do that anyway and so this reminded me to set up the facility; that way it will be able to handle other station names where there needs to be some special treatment.
It's not easy to get that one to come up to debug it, so if anyone gets that one, give it a try and let me know if it's okay.

But which rulebook would you use? Sure the L'Enfant variant could cover the oceanic disconnect from Mornington Crescent, but unless we get a new North American/European connection, we'll need to make some revisions.
(Also, the "inbound/outbound" terminology can be somewhat confusing)

I'd been harping on the Captchaskljasda thing for awhile.
This is almost fun!
I like someone's suggestion to NOT give a map.
Or make it more gamelike to have the map automatically hidden so that we can try our metrorail knowledge before seeing the map...
THANK YOU.
Awww but then when I failed (because I forgot to put the first 'n' in lenfant) I get the bad old Captjasdhlaskjd.

Nothing to complain about with this, though.
BTW, mine is "What Metrorail station is between Crystal City and Braddock Road on the Blue Line?"
I'm entering "National Airport"...
...and I got an error message.
Now entering "Ronald Reagan Washington Nation Airport" *sigh*...
...and it still doesn't work.
By hitting "Preview" first, I was able to get a reCaptcha. Fingers crossed...

I suppose if you really wanted to make it hard, you would take away the map, which would effectively limit posting to locals (or those who could bother to pull up a map) but there are parts of the system I rarely ride, and I suspect that this is true for most people here.

I don't know how much traffic is enough traffic to make that worthwhile for a spammer. But you could make it much harder to beat (and also much harder for you to code) if you used a customized, randomly generated map each time.

Potomac Yards? (Just kidding - sort of)
I'm a little dubious about this new approach because not everyone who posts here is that familar with the DC Metro system. On the other hand, it could lend itself to a April 1 captcha subsitute of 1) The NYC subway system or 2) a fantasy DC Metro system with a re-routed Blue Line, completed Silver & Purple Lines.

But also, once I've built my own captchas I can easily add new questions that could be harder. Or even if I add ones that aren't harder, if they write custom code, then I can add new ones and they'd have to again, and so on. So it becomes easier for me to make the captcha harder or just change it around to fool anyone who's for some reason taken the time to crack it.
@MLD: This is another advantage of switching to my own captchas. ReCaptcha wouldn't allow 2 on one page, but the way I've coded it there should be no problem doing that. This will allow me to have a petition form and a comment form if I want to.

1 Do you have to spell out stations fully ?
Can I put rd or road, ave or avenue, sq or square, hgts hts or heights, u or univ or univerity, sta or stat or station, plz or plaza
2 Hyphens
3 Large and Small names (Gallery Place Chinatown, Noma-Gallaudet New York Ave or Addison Road Seat Pleasant) would it accept Chinatown or New York Ave if someone put that.
4 Name changes to stations Noma (WMATA site gets confused if you put NOMA in the trip planner and will ask do you mean New York Ave)
5 If there is ever a question asking about how you would get to a place via rail please take note that there are anywhere between 2 and 4 options to get between some stations
6 Inbound/Outbound, North/South, East/West could any questions involing them be specific to the lines cause some trains do travel north for portions going south or south when going east (Blue,Orange lines between Rosslyn and Minnesota ave or Benning Road or the Green line between South Ave and Naylor Rd)

What about the blind? While text is available, it would likely take them at least 5 minutes to pull up a textual "map" if they are not familiar with that part of the system.
Use of "outbound/inbound". For a public website that attempts to reach a broader cross-section of the public than just transit enthusiasts and urbanists, the use of the terms outbound or inbound is jargon that they may not understand. For example, if a person lives by Eastern Market and works in Rosslyn, is their commute inbound or outbound?
Use of directions. Not everyone has an internal sense of direction, like I would guess most people posting here do. While it is easy and intuitive for most of the regulars here to point to the north even if they were spun around blindfolded, for some they are absolutely clueless about what direction they are even facing! Besides, what direction is east from Arlington Cemetery? An argument could be made that both directions are east, depending on how you look at it!
While the concept is certainly an interesting one, I feel as if it falls woefully short in many areas, in ways that create a feeling of exclusiveness. As an example, if a main national paper happens to link to a post on GGW, then readers would be drawn from everywhere. If someone has never been to DC, and isn't naturally fascinated with transit or maps, how are they to be expected to know where a station is, what direction is north, what the map they are looking at is even about (!), etc. As mentioned before, it is about as complex as the "European or African Swallow" skit by Monty Python to many people.
REVIEW PAGE EDIT: "U Street" is not an acceptable answer.

"What Metrorail station is between Cheverly and New Carrollton on the (full time) Orange Line?"
How is someone who does not know what Orange Line the site is talking about be able to tell which one is the full time one, and which one isn't. One may suggest to look at the map if they do not know, but if you open the map there is no legend! Basically, that question asks someone who may not be familiar with the system to take a blind guess.

There is only one place where those stations are though, so really even mentioning the line is redundant. You don't have to know which part is full time and which is rush-only to identify those two stations and see which one is in-between.

Or forcing email-confirmed accounts on people with a 24-hour waiting period before first post?
