They could implement ways to identify afk'rs using scripts not to be kicked - from other players being able to tag them to automated internal processes to help identify them. GM's could check tagged players and if they are found scripting to avoid the afk boot then suspend the account for 6 months - no appeal. The vast majority of the players doing this would not risk it and stop. Right now they are easily found and doing something obvious like jumping 3 times every 10 seconds - and this doesn't account for the people inside a house doing it out of sight. Right now by what I read we are only allowed 750 active players per world - and I'm sure a chunk of that is taken up by people afk scripting so they don't get booted because there is no downside if they are discovered other than being kicked by a GM.
