It's not an abuse to give mass negative if it's a proven scammer, sometimes it's better to do so as the DT network is very dynamic now and the feedbacks can jump between trusted and untrusted after monthly DT1 updates by theymos.
I see and in case of scammers I totally agree. But beopen is not a scammer, he is respected member. It looks for me more that he is pursued by group of members, which were judging him earlier and still can not forget him, even if he was already painted and almost disapeared from the forum.
