That's a rude and inappropriate way of fetching data after sending out a formal request asking to stop downloading.
Shame this went the way it did, but I think the decision made by PBBans on this matter is the right one.
According to the votes/replies in the topic/poll regarding the downloadable banlists that MaydaX put up this morning, the admins that stream to PBBans will fortunately not really suffer from this.
