This game has a really nice community. I haven't had one person verbally harass me yet. The rudest thing I have had happen was people leave instead of just clicking the auto-forfeit button, but that's not too bad.
"watch out for ghosts"? do you mean listen out for ghosts, i would recommend using earphones or head phones when playing this game so you can more easily tell where the ghosts are coming from. (they make a creepy humming noise, so even if they are on the other side of a wall, you can keep tabs on them.)
This comment is pure awesome. :-) We think the community is pretty great too, thanks for saying this!
