I have been playing the game Runescape now for about 1 1/2 years,
almost 5 to 6 hours a day. I have build my account character with high
stats, and spent COUNTLESS hours of doing so. As you may know, this is
the only game that is COMPLETELY impossible to cheat on. Thats why my
high account is so valuable. However, my ccount has been banned.
Recently, I ran a macro which moved my mouse cursor around, and played
the game for me. Apparently, they have some type of macro detection
system and my account was banned for that. How do I get my account
unbanned. I am extremely depressed and would do almost anything to get
it back. On ebay, my account would value for $1000 us dollars.

You can try to appeal, but I doubt it if it would work: the rule
against Macroing is clealry stated on the site (rule no. 7). By the
way, they also forbid reselling the account, which seems like a
violation you were about to commit.
