is pressing a single key continuosly every 1-2 sec not enough to avoid afk? I have an npc selected and pressing the interact with target key repeatedly but I'm getting disconnected from the server after a while.
I think Blizz intorduced a more robust mechanism for AFK where you have to actually do something in the game other than just jump or move a little. Maybe try opening your bag and moving an item from one space to another and back again, or interacting with an npc, or mounting and dismounting. Something more than just jumping.
