Thread:Project:Support desk/Disable edit or createpages by non-users

Finally I have been able to block the creation of new accounts of user, but itself receiving Spam of no-users. I cannot block IPs because they are thousands. There isn't any method to block the editing or creation of new pages? If nobody can create accounts nor is to editing option some of pages in wiki ...where generated those are pages of Spam? ...in the data base?

from where they leave these pages? http://instantaneo.es/wiki/index.php?title=Especial:P%C3%A0gines_noves
