Dumb analogies aside, here is how I see it:

Quicksy is not interested in having all account sellers negged. He's fully aware of the gray areas and changes in how account trades are perceived, etc - what with being a major account farmer/trader himself - so he's just using this as another attempt to undermine the credibility of some DT2 members and either compel Blazed to dump them (seems unlikely) or compel other DT1 members to exclude them (had mixed success with that in the past) or compel theymos to dump Blazed (not sure how likely).

Quicksy is not interested in improving DT. He'd rather let hundreds of scammers lose their red tags as long as he gets what he wants, whatever that is.
