Your chance of being banned is a complex formula.
First you start with the chance of using a bot on an established game that does not allow bots, then you add the high probability that your bot will get stuck at some point when you won't be able to get it unstuck fast enough, then add in a high risk factor for every minute you aren't watching your bot to stop it from doing stupid bot things, add in the amount of auctions you post beyond the safe limit, add in how often you post these auctions and on what toon, don't forget to add the percentage of jealous botters out there that report botters because they are simpleton greedy jews, then multiply the entire formula by the amount of hours you bot in a day and then divide it 7 and multiply that number by how many days you bot.
That is the super accurate formula for figuring out if you are going to be banned for using a bot. I hope you're good at math and determining unknown variables because no one knows.
The rule of thumb is if you are doing something wrong, you have to be ready for the consequences. Keep that in mind young one.
