I do sometimes wonder about the inbuilt mouse method as I often witness it hopping to coordinates instead of moving smooth.
I also have some code I wrote last week and my old account which had not logged in for a week or so got banned within 2 hours, whereas my 2 new accounts have been running almost non stop for a week now. Brand new accounts botted from tutorial island. The only thing I can think which may have flagged it was the transfer of wealth from the old account to the new ones.
Anyway, we will see how it goes going forward as I've implemented new interact methods with a custom mouse algorithm now.
