Runescape bot rollback and xp loss?

I've been caught botting firemaking on my account and got a macroing minor offense and my account is temp banned for 14 days. My ban is almost over and in really nervous because I've heard of Jagex taking away xp that the player gained through botting. Is this true? And if it is will they rollback my firemaking to the level it was before I botted(71)? Or will they do a complete rollback on my account back to where it was before i botted?
