I know I've accidentally lured ants into hampshire before with Talan. And believe me, it wasnt because I was running from them.
If someone spawns the ants before you and doesn't fight them (can be done just by walking by a little too close.) They spawn and wander around. If some of them wander between the hill and tha hamp wall, and hang out there as you walk by, they'll spot and target anyone that runs into hamp just before they hit the door. So, unless your machine is reallly slow, you load through 10-20 seconds before them, and continue on your way.
I was going to the craft hall, then realized just past the monument that I needed.. I dont know, some kind of tool or oil, so i went to the temple of deliar, and here was this ant loping into town making a beeline for the pawn shop.
He never got that far, but he didn't have anything great to unload either, so I don't know what his hurry was.

Edit: er, my point is: with ants, i'd give people the benefit of the doubt. However there ARE a lot of blatant examples of this happening. This one could easily have been unintentional though.
