If a woman said that she had a stalker showing up everywhere she went,

Yes, that's a big issue, but it's not what's happening.

She said she doesn't know where they are located because the harassment happened virtually.

Very different to say "I had people threaten me nonspecifically online" vs "the police followed me home"

I completely disavow all state repression. These people seem very intimidated and they should feel safe, but I could list a litany of awful shit the US has done with far more concrete evidence. (I really don't feel it's necessary and it would just get dismissed as whataboutism anyways.)

However I don't agree with extrapolating a testimony of online harassments into some narrative about how these aren't just random civically-minded volunteers but a vast world-spanning conspiracy to surreptitiously kidnap offenders. It's unfounded and the fact that the link you provided is citing elected conservatives demagoguing should really cue you into that.
