I've never gotten this to work, but other players have reported it in years past. Whether or not it has ever been nerfed, I don't know.
There is an old exploit that can lag out the entire area you're in. It's a self replicating macro. This can lag you and all players in the immediate area out to the point of the game crashing. If it still works, AFK players won't know they're no longer online, and the spawn will be freed up for your taking. Rumor has it that it can even lag out every player on the same planet to CTD.
Name the macro Lag, assign a speeder or droid to the first tool bar slot (for this example only, however you can put it in whatever slot you want).
/ui action toolbarSlot00;
/pause .1;
/ui action toolbarSlot00;
/pause .1;
/ui action toolbarSlot00;
/pause .1;
/macro lag;
Keep in mind this exploit is several years old and most likely nerfed. In fact, it's so old I'm not even 100% that this is the correct macro lol. Sad to say, I don't have much else that would be useful. Can't even /report AFK'ers anymore.
