I had just finished a 20 hour run with it (with a 5 hour break ever 5 hours) and not been banned, also been using it since 50 agility and am currently a little way from 78.
On a different note, would it be possible to add alching to the script? So that in gaps during roof-tops it alchs a selected item? It would give it a really good selling point on top of it already being an amazing script. Just a suggestion.
