Something similar just happened to me, there was a strange person outside of my plot, looking to trade (twas a trap however). After a few minutes of talking to the first guy, another guy agro'd me from a few screens away, his portrait wasn't even there just after the agro.
Found no scents with 180 x 120 per/exp, walked for about 5 minutes in the direction the ranged attack came from. My polak friend and I swapped external crossroads, I believe he also gave one of his cr's to York, which probably means AD has access. The trader being Russian, this makes the most sense to me.
I'm now 100% sure that it wasn't AD, saying it was without evidence was a mistake on my part, AD have some of nicest, most helpful players in all of the game.
