Seems like jagex detects it nowadays(pattern/coz its way too fast/non-human-like?), got banned for it on 1 account, decided to make sure it was this, did full clean of caches(jagex and CCleaner), hwid and hdd id change, bought new private sock5 proxy etc. no trace of the pc, ran this till level 33 woodcutting/40 fishing only = account disabled after 2 days inactivity, too bad, was a good script.
Hopefully u can find a way to fix it
