Gamemasters used to ban players who used illegal softwares to level (if I'm correct). However, now they have something called 'mass bans' which is a mass ban of players who use illegal softwares to level/bot. It's rare to be on this list. Nevertheless, if you bot 24/7 with very low stamina, then it's more likely to be on the list, but it's still hard to be on the list. The reason why it's very hard to be on this list, is because Tibia has a big population of people who use bots. Nowadays, it's hard to find people who level manually. Anyways, as @Elvang said, it's very rare that a CipSoft employee comes to you and it wouldn't happen anyways, nothing to worry about in that case.
