New User Flood
The highlighted comment was created in this revision.
There seems to be a flood of new users, I can only guess that these are not people interested in robocode, but rather some kind of spam bot (or spam bots). We need some way to captcha user creation I think.
While we are at it, remove some of those "new users" without any edits.
Well a few, for example I don't have access to actual site stuff (so I can't add a captcha).
We could just go through and manually delete them all, but there is no bulk method way to do that (that I know of).
List of those with mediawiki "administrator" access:
AW, Chase-san, Darkcanuck, David Alves, GrubbmGait, Jdev, MN, PEZ, Rednaxela, Sheldor, Skilgannon, Skotty, Voidious, Wompi
List of those with server shell access:
David Alves, Rednaxela, Skilgannon, Voidious
The one whose name the server name is under:
David Alves
The one whose name the domain name is under:
PEZ
The last several times the server needed config maintnance I've dealt with that. I know Skilgannon is also checking in wiki sometimes. Voidious less often recently to my knowledge.
Hate to break it to you Chase, but we already have a captcha on user creation. In fact, we have *TWO* captchas (reCaptcha, plus a simple math question presented as an image) required for user creation, and the bots involved in these user creations seem to crack crack both. I tend to wonder if they're using a "mechanical turk" type of system to outsource bulk captcha breaking to humans.
Only reason they very rarely succeed at actually posting content these days, is because of a custom Mediawiki extension I added, which blocks any edits which add new external URL links if the user account was created within X hours of the attempt. (Note, it does not block external URLs that are not formatted as Mediawiki links, such as the participants page of course)
Perhaps I should augment this extension to remove users whose only attempted edits during a 1 week period were blocked in this fashion?
My experience with captcha locked registration, is that at some point someone, most likely a human, provides an answer to at least one question. After this bots will register like crazy. On my site I had non googlable question, which holds bots for a month or two, but sooner or letter they will come.
The only way to deal with it, is to remove old questions and generate new ones.
