The only information I have run across related to gang-stalking appears on disinformation web sites that seem specifically designed to mix truth with obvious fiction in order to turn people away from truth. These are essentially behavioral engineering "news" sites that feed new memes into the public consciousness, in efforts to further condition and control mass consciousness. PsyOps and propaganda, essentially.
That said, your posts may in fact be a similar effort to discredit the content that appears on these forums. Traditional Catholics are an obvious target for the soft communist disinformation propaganda machine, after all.
The only people I have met who share similar experiences were people damaged by long-term intravenous crystal methamphetamine addiction. Paranoid schizophrenia was the result.
If people are in fact stalking you, which in fact may be the case, I would arm myself with a gun after learning how to use it properly. A long concealable blade or stun gun may be equally effective. If someone tries to hurt you, then defend yourself. If these stalkers never actually attack or harm you, you may want to smile every time you see one, and invite them in for coffee or tea.
Or, learn to stalk the stalker. Capture one. See how it works. And pray for them.
