I think this will be related to trust and whether there needs to be a cross-forum DT policy? It sounds crazy, but the thought was actually in my head
it is not necessary, the Bitcointalk forum does not have a partnership with the forum. if what happens is buying and selling accounts on this forum, that's a problem. but if what is being sold is an account that was teleported to the forum, then there will be no problem with the admin or DT members on this forum.
let each forum handle its own problems. with the existing regulations and rules in each forum. there is no need for a cross-forum policy.
