[CLAM] Spam on the wiki

[David García Garzón]

On the past weeks some spammers created quite many accounts on clam-project's 
wiki and filled it with spam, again. So the requiring login, valid email and 
captcha seems not being enough.

My apologizes for the inconvenient both for the spam and the measures. The 
wiki should have been restored. Warn me if you still see some spam or i 
deleted more than i should. ¬¬

If you know any way i could further protect a mediawiki site against spam 
without fully closing it to eventual editors i am pretty open to suggestions.
By now i just made the wiki send me an email on any modification, so, at least 
we could react more quickly.

David.
