I'm sorry for your loss - I suppose al-kharid is a bit of a botting hotspot, it might be worthwhile to move to a slightly less conspicuous location. Unfortunately bans do happen and are certainly common on newer accounts.
To answer your question: anti-ban procs at a completely random rate (between 1/60 and 1/100 chance of proccing every second). I'm leaning away from increasing this chance as I don't want to create regular, detectable movements, but I think the rates are reasonably fair as they are.
