There are thousands of "groups" on this site.
Imagine the chaos if even 10% of them had the temerity to post recruiting ads?
Even worse, suppose Erik took time out from all the site improvements he's working on (I hope), to 'lock' ads of this character?
We might never see the Live Chess tournaments working flawlessly.
