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.
