No, the vast majority of “trusted” users here don’t scam, but I would say many many bend their ethics a bit here and there to comply with some of the more heavy hitter “trusted” members for reasons of gaming the system, including getting accepted in signature campaigns, hopes of being or staying included on others trust lists to climb the ladder, and generally to get in the good side, or not get in the bad side of other powerful users..
Not scamming necessarily, but maybe not speaking out against other certain users or projects, and/or swapping +trust or inclusions with others they don’t really really trust or agree with just in effort to climb the ladder themselves..
