There's recently been some debate over what kinds of restrictions there should be on what users include in their profile pages; the original post caused a lot of controversy because specific users were brought into the discussion as examples of having inappropriate profiles. It has now been deleted (it was closed, and two delete votes were already cast; I cast the third and final delete vote).
So, let's make a fresh start. There will be no discussion of any user's profile here.
Should we have restrictions on what users can include in their profile page? If so, what should they be? If a user is found to be in violation of the restrictions, what should be the consequences?
