OK, a little detail on the whole how I came across this strange kid. Alert ended. I go to the bathroom. Come back, this kid is doing this across from me. So I decided to record him / her / it? I always wonder with the actions some players do in game. Are there NPCs in planetside 2 that we don't know about?
Possibly someone who went AFK but didnt want to be disconnected and risk getting stuck in queue's. He has a macro that passes several actions so he's difficult to spot by automated systems while keeping himself in that corner.
When I know I'll be away for a bit but an alert is going on I stick something into my keyboard to hold down the W key and just stand next to a wall on the warpgate. This there is just the more complicated version of "sticking around".
