I've heard about him and seen some old threads about him. I wasn't there when it happened. I didn't see the saga play out in real time and there's probably a lot of threads and IRC conversations I missed.
Xuphor pretended to be a girl with lung cancer in an attempt to get attention and sympathy. Members pointed out holes in his story and he eventually confessed it wasn't true. He was banned a day or two later and has been infamous since then.
Can't find any threads about this particular issue on GBAtemp or the wider intarwebz. Saw one video on YouTube that seemed relevant, but it was some dude with the same issue, no solutions offered in the comments. :/
