I don't understand why people say that you will get banned because you got rolled back. Getting rolled back is not some marker so they can come back and beat you up more later. The roll-back IS THE REPERCUSSION for botting, its taking away the experience that you got non-legit and also taking away most of the recent xp you got at all, so even if you did some stuff legit its taken away as punishment.
The roll-back is a way for jagex to punish players for using third party software to advance themselves in the game unfairly without stopping the income flow from that persons members account. If there is a mass-ban at all come February first, I wouldn't think for a second it would span past f2p accounts, as banning them has no profit reduction downsides like banning a bunch of members accounts does.
I think you will be fine, my maxxed pure got his theiving rolled back a few months back because I used a BETA which was stupid I know. Thieving went to 10, as well as firemaking to 10 and agility to 10 even though I got those WAY back, and my 99 magic went to 93 (this was a slap in the face because it was directly before barrage....), 99 range to 96 just so I wouldn't have the cape anymore and 75 attack to 74 (which i didn't find out until I tried to wield my AGS in wilde, also another slap in the face to reduce it so little as it was never botted, LOL).
All in all, if you have been reset you are lucky you didn't get banned at the time but i doubt they will add insult to injury by allowing you to continue work on your account after having massive amounts of xp taken away just so they could ban you later even if you havn't had another offence.
