It's definitely a client problem.
Since the past last week every account that logged on Tribot client got banned, regardless if I was botting or just transferring stuff to my mule account. Also during the same weeks I've been botting alongside with OSbot and that account has not been banned (8-18hrs botting) I'm not stupid when it comes to botting as I know the best times when to bot and how many hours to bot. Since last year I've been botting during the best times and not once until now did I get banned..
tl;dr tribot client needs to get fixed somehow
