Used the script for 2 - 3 hours yesterday, 45 - 49 ish minutes per session, with 9 min +/- breaks in between, and a random manual break. I used injection mode by the way.
Just tried to log in, account perm banned. While running script yesterday I was stringing magic shortbows. In between banking every crafted inventory of bows (deposit inventory), and withdrawing 14 bow strings and 14 magic shortbows (u) the script would take a moment, which I found to be a little strange. The time it took from action A to action B was almost everytime the same. I'm thinking this might have gotten me banned. Not sure though. Maybe it's something you can look into. Hope this helps, and awaiting your reply.
