when reporting, about how long to wait before gm response (if at all)?

Oh, no they most definitely act on these kind of reports. That other player will likely take a ban for this. Especially if they used strong language.

Really? Huh. I was crossing my fingers that they at least got a warning. Have never experienced being singled out in the game like that before. I couldn't even respond back I was so shocked. It was really mean-spirited, and yes, there was a great deal of strong language.
