New User Flood
Account creation is re-enabled.
I removed reCaptcha but in exchange made the math question slightly trickier. I also obfuscated the input field name to be a random string, and added two decoy fields like you mentioned Chase. One decoy is also named with a random string of the same form as the real one (and the ordering in the DOM is swapped at random), and the other decoy has the fixed field name that is normally used for a math captcha on Mediawiki.
We'll see if this keeps them out.
While I was at it, I also cleared out inactive users with a maintenance script.
Oh thankyou. That big list of names on the change log was causing me grief (and it made the atom feed about useless). Let's hope that this stall them for awhile. It isn't like they were able to post anyway, but the registration itself was getting annoying.
Thanks for the changes. It is nice to see only relevant changes in the log.
