Though the risk of the channel being the victim of a Google ban-hammer goes up given more contributors. Assuming some incident in which Google's response is warranted, they won't care if told that it was one "bad apple". Chances are they'll hit the channel (and in typical megacorp automated governance mode, not hit that "bad apple" user/contributor).
If Google were smart, they'd see this as an opportunity to "do better" and facilitate these kind of co-ops, with appropriate technical, financial and governance support.
