Was it death valley? He posted his thoughts in b&m as well:

Overall it's the b&m regulars that don't want the bad beat stories not JBB. His points on illegal card rooms and underage playing are misguided as well. It's specifically the 2+2 administrators that did not want fake id's etc discussd here and i understand that. If we don't put it in harsh words in the sticky people will continue to post about it. Not discussing illegal cardrooms openly benefits everyone.
It's possible that JBB could have worded it differently and just said they aren't allowed instead of threatening banning. I'm not sure which is better but his current sticky seems to get the point across pretty well.
