No good scammer that should never be trusted with any amount of cash in runescape. He has scammed nearly 500mil+. He will befriend you one moment, and backstab you the next, don't give into his lies, he may convince you otherwise, but in the end, you'll just be his next victim. The only upside is that, he believes that runescape is more than just a game, it's his life, preserved in a server somewhere. This brings me, and many others great joy, because the more he scams, the more he is sucked into this imaginary world, and the more 'real' life he loses. Let's just observe him, slowly killing himself, and enjoy it. Doesn't that just make you feel all warm inside?
scammer, loser, child, immature, cunt, prick, tool, hillbilly(I mean have you seen his commentaries?), ah, I could go on for a while... but you get it fat man cake

When someone you know, e.g. A peer, takes a dump on your personal belongings on your birthday. Also he then smears it in.
I can't believe what happened on my birthday dude, Stewart took a big fat jobby cake on my brand new macbook pro .

Totally gutted.
