That's what I was thinking. It would be abused, especially for flaming and such.
I don't see how it could be used for flaming, but anyone who did manage to start an argument out of it is far too immature to be here anyway.

I log in "invisible", and when viewing a thread, moderators see me as an "anonymous user" (or some such term).
I am pretty sure admins and such levels can actually see me, though.

By default, IPB allows the root admins to see the people who have logged in as anonymous on the online list. No one else can have that access unless Neowin has used a mod to give other groups the privilege as well.
