My understanding is nothing says "disallows anonymous access", it's all about not collecting IPs from children, or people that have a likelihood of being children over a certain threshold.(If I'm wrong, please correct me!) Editing obviously records your IP. They just chose to turn off IP editing on susceptible wikis, as opposed to doing a number of other things, such as a message making one confirm they agree to the TOU (like you do when you sign up) like Wikipedia does with anonymous editors.

Funny though, that their reasoning for not having a click confirm on editing was that "COPPA called it out specifically", as if they weren't allowed to use that, yet a NUMBER of other sites are still using it... like Wikipedia itself.
