Something I've always done is just apologizing for it. Just state that you made a mistake that long ago and that you have learned from it. Also make sure to say that you plan on playing and will buy membership again. Jagex usually accepts that.;P
first of all, change the password by different Ip address, (not your city, better other country ip)
2, send appeal, claim you got hacked, and tell jagex your account got disabled while someone else hacked your account and caused that. you are innocent,
now you heared old school is back, and you want back to play it. so please help.
this is 70% success. rate
