I have first hand experienced some of this as well but I knew the individuals and their intentions and I learned to tolerate it as a temporary thing and move on with life. It really really messes with your head when you incidentally and actually find a RAT, for non-technical people they have no idea what that is, they just know somehow their most secret moments are known to strangers.
For those unaware, there communities of "underground" creeps that RAT people (usually women though) and share this shit between each other. I'd imagine these are also the same peope that are into gore and other messed up stuff?
In short, other disturbed people sometimes (but not always) cause people to think they are victims of gang stalking and sometimes they are not wrong.
