In my experience, anonymous trolls and spammers usually go to town for a few minutes to an hour, then don't come back. Trolls want credit for their trolling, even if it's under a name no one knows is them.

By far the most problems I've seen on Wikia and other such sites has been with registered users.

I've seen many admins who started anonymously. I did.
