I think you should disable that "other users" section Marty, everyone (including me) will complain about it sooner or later
I know I am contradicting myself (since I did it), but it's not a good idea, really!
Hehe you should see the list of default features you can buy, it's madness, madness I tell ya! I've disabled most of the features already actually.
They include:
Create a forum
Moderate a forum
Change a forum description
Password protect forum
Ban a user from forum
Ban a user from thread
Fire a moderator (Blasphemy! hehe)
Delete a thread
...and the list goes on.
Actually, looking at the poll I think it's pretty clear already that people don't want the steal option so I've removed that. I've also removed some of the Other users options as you suggested, good idea.
Summary:
* Stealing is no longer possible (also, steal protecting option has been removed)
* Changing the avatar and usertitle of other users is no longer possible
