I have had the same issue in Fractals LFG. This same guy, that keeps joining party. Changes the LFG, pull down the LFG. He has been doing it a total of 3 times. Last time, my friend and I decided to try two hours later. Guess who joined again, the same person. He has been trolling other people as well, because I received warnings from other people in LFG, that he is there to troll.But two hours later, he is still joining our group and changing it, pulling it down, trying to kick members. Of course I find it annoying. But I feel bad for that person/troll, if he still keeps an eye on people after that long a time. He must not have a whole lot of other stuff to do with his life. Which is sad for him.
