[Mediawiki-l] jibberish

[Eric K]

I think making an IP do a captcha on its first edit only would help. The captcha would keep a record of the most recent IP's in a table and if an edit hasnt been recorded from them, give them a captcha, otherwise pass. This may mean the IP table would grow large (may not be fast for large wikis with lots of editing), but purge it a certain period (15 days etc). Captcha has to be there one way or the other. This is least irritating.
  There is definitely no way to check if an edit is spam or not, except for capthcha.

Not here. I set anonymous edits to false and installed reCaptcha.

Installing reCaptcha doesn't really constitute a big change to the
wiki (its quite unobtrusive really), but disallowing anonymous edits
is a pain. This is especially true of pre 1.11.0 MW versions where
'view source' doesn't seem to work 'out of the box'.

In theory there should be a simple SQL query to detect these kinds of
spam (one nonsense word at the start of a page) - However, it seems
better to code a general solution that highlights potential spam for
review. Its keeping track of the potentially spammed pages that I find
most difficult.

Anyone handy with Bayesian filters? If we could rank edits by
'spaminess' using a Bayesian filter, and be given the option to review
the top n most spammy revisions (with feedback training) ... well...
that would be great!

Send all your edits to a gmail account and only allow those that get
forwarded back?
