Take a walk a round the cities/sanctuarys/towns you can see MANY people afk, and walk by them an hour later and still in that exact place. People are abusing the fact they don't get logged out, and staying logged in.
I knew I'd be out of the game for 3 hours, but for this very reason I didn't stay logged in. It's unfair to people trying to play. Not to mention if a lot of people can't get in, they may give up soon, and that means less people to play with down the line.

EDIT: Not to mention people in INN's for rested.

There aren't many bots, this game isn't economy based like XI or even as influenced by it as other games like WoW/Rift etc.. Been specifically designed that way, less demand means less need for supply, means less bots.
Just ignore them, and hope to god not too many people start complaining, or SE might do something stupid with how much they hate RMT, and have that huge collateral dmg issue XI had a while back where a whole bunch of innocent people got banned for a long time.
