Not your fault man. Its the risk of it.
I have been using Sub Mining, and Lost Wintertodt, but I use those daily for going on 2 weeks. Ive also used them on multiple accounts and the only one that got banned (so far) is the one i used this script on. Like I said, its my own fault. The script worked flawless tho.
Edit: Wouldn't feel right to me to not include that I did use the trials for all three construction scripts almost consecutively (within 2 hours) of each other. Could've been that they picked up on 3 different mannerism, or play styles, on the same account doing the same task.
