Perry
In my desperate attempts to find good RP's I have seen some unpleasant stuff I have mostly managed to forget, but there is this one case I shall never forget. Out of boredom and spite I once joined this RP which was kind of a teenage attempt at bringing Harry Potter and Vampire Knight together, with royal blood vampire boarding school and I thought it was a perfect opportunity for me to bring a nice pile of dirt to their doll house. (Yes, I am that kind of asshole and pretty good at it.) So I unleashed a world of political conflicts, torture chambers and social controversies and was surprised to find two other players with similar intentions.
What I meant to say is that it led to me getting to know a class of players I would not have known otherwise. People - no longer teens themselves - dreaming of glittering royal societies and gossip-ish stories. Among them was this one with a good number of characters, whose concepts sounded fun and pretty diverse and she was pretty good with grammar and basic writing skills, and over a couple of years I had to watch in amazement how she molded all of them into the same pitiful, whiny, over sentimental teenagers (even a supposedly scary 800 years old vampire) who were hurt and misunderstood. And besides she bullied the players, trying to tell everyone what to do and how to play, believing every genuine idea could only come from her. Funnily she believed I was there only to "ruin" the beautiful RP, and changing rules by the second just to torment her.
