As the leader of Please Be Careful/Dragongod Knightkings, the twin Something Awful Free Companies, I can confirm that this is the case. Some members are remaining online to ensure they can play when they have free time.

However, I don't believe that members of PBC/DGKK are the only ones taking advantage of the lack of an idle timeout. This is a problem endemic to every server and community, and will regrettably continue to be so until either the severe login restrictions are lifted or an idle timeout is added.
