Well yeah they might appear if you re-open the pvp tab I'm not sure but it's really glitchy and you can't really see which team they'll be on anyway. Plus some people will decline/be too slow to accept and get replaced by others and since joining running minis works properly again it's not exactly hard for trolls to get in :)
And it's worth mentioning that on either server there isn't a large number of minis running most of the time, so declining one can mean a long long long wait.
