So, as you know we are strict against botting.
Now without getting into too much detail, we know for a fact that these characters were botted on briefly and that these sessions were not to your knowledge.
However, we also hold people responsible for their own account actions, and do not support account sharing, so even though someone else was autoing you are responsible.
After discussing it with staff, given the history of how much legitimate time and effort was spent on these characters, we will be unbanning all three.
HOWEVER, this unban will come at a price.
Each character will have its thieving reduced by 13,034,431 xp.
That is the amount of XP from 1-99, and seems an ample punishment for your irresponsibility in sharing these characters with someone who decided to use illicit 3rd party programs, however briefly.

Welcome back.
