I figured that I could do something with forcing the character to not sit but it's impossible! x.x They do it with code that's not in the API, I've hooked and disabled every form of API sitting and yet still the character persists ...
Check out "tradedispenser" mod. its on curse (even tho u hate curse)
Im a mage. I sit on the AH, afk. I automatically announce that im handing out water. When someone opens trade, i auto put water in trade and trade
All this can be done afk, and the talking keeps me not-afk
maybe make it so that your character /dances or /say something every so often? Say something stupid from ascendent every 14.9 minutes? :P
