I think it's because even though you're not PvPing against some of the people in there, they can't get out if they wanted to. Considering most don't have acceptable magery, I'm going to guess that is the reason..but it IS guarded, and I do see where you're coming from that it's comparable to brit bridge..but them not getting out of the mine might the reason.

Nevermind. The boss said it's legal.
