I spend a lot of time doing peterstuff.
The history is that Robert is and was besotted with Omega, but she was shagging Ascan and keeping it a secret from Robert, so he kept following her around the board like a horny puppy. The rest of us thought this was rather unethical of her, since it would be better for Robert to be told the truth and get on with his life, rather than to be constantly obsessing on someone he was never going to get anywhere with, but she kept avoiding the issue, and manipulated him into thinking that we were spreading malicious rumours and that there wasn't anything between her and Ascan.
Also, Robert was generally a sickeningly horny, pathetic sap around the females on the board, and when Purposeful Insanity, Dunc's wife, suggested to Robert that his behaviour was putting people off, he got very upset and viciously attacked her over it, then Dunc called him out about it, and ever since he's referred to Dunc as Duncshit.
There was an incident too where Laz told Omega that me and HG (an ex-member here) had been making fun of a pic of hers. There was some truth to it (she really does look like a man), but also a lot of distortion, and outright lying by Laz, since he had his own agenda. Through that incident, it emerged that Omega was quite manipulative, and she left the board soon afterwards, taking Robert with her. Dunc would be able to tell you more about Omega.
I don't know Ascan's story, except that he's a paranoid jerk who seems to have always had a thing against us.
