We have been plagued by several newbie looking AV's that land on our parcel, they have no profile, they never answer your IM, they just turn 360 degrees and then poof, we have moved 3 times to different parcels and the same thing happens on all, some of them being the Same av''s, Is there some sort of spying going on ? Are there remotely controlled bots that are able to gather information on folk?
