I understand completely why the complete rulebook on how you can't and can't promote your posts isn't posted clearly on the site. Voting ring suppression is an arms race, and posting the current rules helps the vote-ringers.
But a general statement about not soliciting support for applications could have been made clearer. And, more importantly, the vote ring really had nothing to do with this. Kevin Hale didn't want Maciej in the program. That's all there was to it.
