Why? The feedback lightlord left doesn't look terrible and certainly not abusive.
Because people are not being excluded from DT just because of their abusive feedback, but it's my personal opinion and I see that other members excluded him also.
Lightlord has nothing to do with the spam, that's 100% on the manager and participants. That's why there is a manager, although everyone has a different idea of what is considered spam. Best thing users can do is report posts and hurt spammers by getting them banned. As far as the trust list goes, I really see nothing wrong there, just because a forum mod doesn't trust his is not a reason to halt a campaign. Long as he pays regularly and on time he's fine. Just goes back to respecting people.
He is indirectly connected with spam, because he hired the manager and he made those low payment rates, so much that seeing these avatars and signature you mostly expect to see some low quality posts.
