Itâs because they do not seem to have programs to differentiate you from a bot.
In town, many people AFK, itâs common practice, and youâre not actually using your toon. You are just sitting there. Same could be said if I sit down on a field to take a break from grinding and go get a drink of water as a Corsair. A GM wouldnât bother with this. However in the case of Sorcs/Necros, youâre character is still killing mobs, and all you need to do is have a auto-pot program. If youâre not actually botting, youâd have to tab in at least every 2-5 minutes. Luckily GM Durian is the patient kind, but that could change, or you could have another GM patrolling who isnât as patient. Either way this seems to discourage it.
Another fine example is people who Z farm by leaving a heavy object on their Z button. They do not consider this botting, but you are not at your desk, and it can warrant a lesser ban, perhaps longer if you are caught doing it repeatedly.
My personal opinion? You shouldnât be allowed to. Itâs really not fair to everyone else out there who has to be present constantly to use their skills. Iâm not vehemently angry about it as some people are, and since it seemed legal for a time I considered doing it myself for some lazy silver. You should check search on here about AFK farming, thereâs some really long threads that goes over everything with both sides discussing it (or, more like arguing it.)
