i blocked all the accounts which edited the 2009 pages with spammy 
links, but i could not revert to the last good release... does anybody 
know how to do it?


also, i think we should disable the "automatic" creation of accounts for 
the wiki.


and find a way to remove all blocked accounts + revert all the changes 
they have done?


does anybody have enough mediawiki knowledge to do it?


ciao
