Oh i think I get it now, its not the words you typed but maybe they reviewed your evidence or something and you got unbanned or.. They recently changed the banning (apealing) system or something and tons of people get unbanned and unmuted.
My fucking god, that pisses me off. I have never gotten an account unbanned for autoing, even when I was genuinely sorry.
Then you go and write mooooo and they unban you. Its things like that why Runescape sucks, they're way too strict with their rules also.
