If they register in a forum or group they should understand that there are obligations they have to carry out. Like in this forum, in each sub-topic there are already many pinned topics and that is the first thing they must steel. If this they do I think Banned it will never happen. In the end it is the willingness of newcomers to learn to obey the rules that have been drawn up in consideration of the progress of a forum. It is proven by the existence of this rule. This forum has grown to be of good quality.
