Thanks for doing this, Mario.

I had already removed like ~30 pages and blocked the users, so what you
saw was only half of the problem.

And we have another problem: The default is blocking a user is to also
block his IP. All users are accessing the wiki through the proxy at
10.0.0.8 and you blocked this IP, this means that ATM it is not possible
to create accounts.

I think a captcha when on user creation should be sufficient.

I have found that an admin-written challenge question on registration is a much better deterrent to spammers than captcha.
