The system bans you only after a number of reports are sent. Dave said that in this instance there were not only a number of reports, but that those reports were from a number of different people. So if one member had a beef with you and reported you a number of times, then it is unlikely that you would be banned. If there were reports from several members about you then you would be banned. But, at least in this case - and I bet probably in any future cases, it appears that Dave reviewed the reports and the posts before the final decision was made.
