I cant take the stupid anymore so either the people who do not understand how a afk timer works are ps3 people or have never played a mmo before. so let me help you understand a few things .
1 running into a wall or holding jump attack or a button down WILL NOT STOP YOU FROM BEING LOGGED OUT.
2 macros can be made but the have be do diff actions and without patterns or they will also be listed as afk.
3 if people log out you will be able to log back in cause spots will not be taken by people who are doing nothing.
If you doubt any of this go make a free wow account or any other mmo log in run into a wall jump in place your call, it will notice you afk and log you out. the timers look for 2 things no activity and repetitive actions.
