It depends if the relay was entered into that alliance specifically to relay. IMO, yeah that can be quite low, but given the current state of ****heads in PA and what they're willing to do *cough*keizari*cough* to win, in relative terms its not.
However, I've heard of cases where some alliance HCs have either "kicked" or disgruntled a member - and even though they might have not been in the alliance for 6 weeks or so - are still so completely dumb to not remove that user from their private channels.
Oh, and we all remember the opportunity jerome and bwtmc(?) were given in Angels attack rooms a couple of rounds ago.
