So who are these members who are demanding to be removed from DT? I've read about people clearing their trust lists (which I've recently done), but aside from marlboroza a while back I haven't seen any such demands. Could have missed it, though.
In any case, I wouldn't even care if a DT member-merit source got booted from the DT list by the community. As long as they're handing out merits appropriately and not abusing the system, they should stay merit sources. Think about how many sources we have now and how long it takes for members to rank up. If you started removing sources simply because they wanted off the DT list, it'd throw a monkey wrench in the merit machine that might be hard to fix.
