People where using jump etc over and over which lead to other people trying many other abilities because they where forced to, to keep up with the others. Now I'm reading Nab saying everyone should be banned. What would SE do? They would have an emergency maintenance and fix it, not ban people for a coding error by their developers. That's a good way to promote the server and its growth. For all we know that was intended.

See: Salvage Bug and the ensuing thousands who were permanently banned on 1st offenses.

Also not the only time they did that. But sure.
