i think jagex doesnt bother reading the appeals, they have bots detect words i guess... put the word "suicide" in a sentence and see how it works out
"Dear Jagex, I am a Runescape enthusiast who has been playing for over 6 years. But my account has been stolen by someone unknown, and if my player is not able to be recovered and given back to me, I will commit suicide."
within 20 minutes my account was recovered and fill in as much info as u can
