I am not sure he was ban or even given tempo ban, I checked his profile and I noticed he made about 2 post yesterday..
OK, a few days was a poor estimation.
The posts were made before I reported his continued violation of rule #3 in my locked reputation thread. That's why I asked. Just because someone has no influence does not mean they can post the same off topic lies anytime they choose.
Most times it could be good to make some topic a self moderated thread maybe to be able control the type of comment that should be coming to that topic/thread.
