Get a bot banned on runescape?

This guy hacked my account, and I've been checking the stats on the high scores and he got 99 mage from 47 in a week, and he went to 66 str to 74 str over night so he's obviously botting, I know this because I added the account then found it on runescape and talked to it for like 15 minutes so, obviously botting, I just want it banned cuz I like earned 99 ranged and 96 wc on it and i dont want him to have that, it was just an old account of mine
