I can't speak for the OP and have never seen the game before, but I think the "in b4 wank" bit was probably just a reference to the fact that RP secrets ALWAYS cause wank, whether their posters want them to or not. The secret is directed at whoever told her the RP was awesome, not at the RP itself.

And your comment was wanky. No offense, but assuming that she thinks she's better than you, that she sees all the players in a certain way, and that she has a grudge against = wanky.
