Badpeteno, wikia use the ip of the user to determ the account. Even if they replace it with text (what is in fact the default). How else can an anonymous user be linked with an pc.

They fix the ip issus by let anonymous be determen by an cookie. But I believe it would be hard to identify an spammer.
