Is this about the Fusker + Fleshlight thread ?

If so, I'll respond.
I'd say it's because they don't want "trusted" sponsors supporting Fusker sites which steal your own webmasters/affiliates bandwidth, while competing with them for the sales. Fuskers steal content from content providers, sponsors, to promote OTHER sponsors. Fuskers can bring a server down in some cases. This isn't "other peoples" biz, as it directly impacts the people complaining about it too.
