this is what happened. i bought **** loads of OP stuff from the /shop and then i shot explosive arrows at him, and then he said "keep trying <3" and then i said like "you can keep trying to get that ... inside your mum" and then he got really pissed.(like on the screenshots)
I think it's trying to communicate with you! I'm currently dispatching a team of highly trained guerillas to translate this worldly alien message..
I think he's trying to say "You suck get a life omfg you can be sooo annoying nobody likes you get a life like you can be so annyoing.." All of that is in caps.. notice how he repeats everything.. xD (People these days -.-)
