So far I haven't run into much creepiness. Less than I expected, anyway.
I play all female characters, all the time, in all MMO's. I have never
run into any creepiness. I think most creepers realize that most of those female characters have men behind the screen, anyways
In my experience, all that stuff happens when a player
admits to being a girl
To be fair, in STO, most players are either busy playing, or in their ships.
