[Pasdoc-main] PasDoc wiki protection from spammers

[Michalis K. <mic...@gm...>]

Hi,

As you may have noticed, our wiki was being hit a lot by spammers
recently. I was patiently reverting every day the spam (and adding it
to LocalBadContent), but with a couple of new spam links every day
this simply stopped working --- too often some important wiki page was
temporarily replaced by a useless spam. And our "recent changes" page
stopped being useful (99% of the time it only shows some people
spamming, and me reverting it).

I still very much want to keep the wiki editable by anonymous, so I
don't want to just limit editing to registered users, not to mention
to some hand-picked users. As long as it's possible.

Thanks to Johannes Berg, maintainer of our wiki server (and former
long-time maintainer of our project :), we now have a simple solution
(advised by MoinMoin developers): TextCha. You will be greeted by a
trivial question on each edit. You will have to answer it, otherwise
the edit will be rejected. You can go on and try editing some wiki
page now; the answer to the question is hopefully obvious to everyone
here :) But hopefully the spammers will not even bother trying.

I don't think this is too bothersome, but still: a few usernames on
the wiki that I remember as being developers/contributors are part of
the TrustedUsersGroup,
http://pasdoc.sipsolutions.net/TrustedUsersGroup , and you are
excluded from this check.
