Have you thought about setting up trail cameras that could capture them making those gestures at you?
I was stalked in July due to some research getting too close for certain people's comfort. Some strange guy sat himself outside my home. Not long after, some guy was casing the windows at 10 at night... things mellowed when I publicly stated that I was dropping the research subject.
Stay safe and stay strong. It sucks people didn't believe you.
Security cameras are definitely on the list of things to get at tax return time... can't afford them right now. Now you've got me curious...what was the research? You don't have to answer if it makes you uncomfortable...
I was looking for advice on what to do and some places say just ignore them, they lose their power if they don't get a reaction. Other's say whip out the camera when you see gangstalkers, they hate being recorded. For my own peace of mind, I've been ingnoring. The other option would be to go sit on the front stoop right now and pretend to be looking at my phone and wait for someone to come by and take a snapshot as they drive by, but that would have my husband worried again haha. Also if they know what I'm up to they won't drive by anyway...
Also the reason my husband wouldn't want me to do it is because he thinks it would be kind of inviting trouble, not because he'd me concerned about my mental state. He and my mother-in-law both believe me now. He was even a little leery of me sharing this article.
