The whole "no self-promotion" bit must be an internal challenge for the Wiki management folks. I have a friend who found an article about himself and his work that had a lot of incorrect information. He didn't know who the original author was. As far as I know he and his business partner encountered no pushback when they went in and performed the corrections (military service, alma mater, more about the business, etc.)

There are levels of editing as far as if you have an account in the community, if you're logged in, etc. It used to be they'd publish your IP address for reference if you made edits on pages when not logged in. I haven't been back for a while but I used to dabble in there periodically. I'll have to see if the account is still current.

If there are accounts that get a lot of bickering they will lock them down and only certain individuals can edit them, to prevent the wild swinging back and forth of versions and revisions and back again.
