Even though I'm rank 3000 & something, I feel that I should defend these ppl.
I quite regularly have a bug which means that when I click 'accept', the system acts as if I clicked 'decline'.
Also, when I do eventually accept, sometimes it just sits on the 'attempting to sync' screen until I click cancel.

i really dont like to deny people eighter cause i like to fight but the only reason i deny people is if i fought u already and u just want revange cause i won and another is if everyone wanna fight me and i just wanna chill and ill fight u later other than that i have no reason for denying anyone.
