Will it make me more likely to get banned if I activate the alert that makes me go to a shop if someone sees a restock in the AU chat?
In theory yes... I mean how many times are you going to know a restock has happened and randomly go to that shop, and buy an item. (if you were a real person) However, I've used this option since I got the program and I've never had any problems. So I'm going to say its relatively safe
Times = Biggest Part. Knowing how to sell the item = Second (Ie. don't throw AB'd expensive stuff up straight away... heck, i usually hold all UB's for a few days to be safe.. Newbs that miss will get jealous and get report happy assuming you're a cheater (which you are XD))
