There’s a lot to unpack here, but it sounds like more than gangstalking, but you’re right about the usual hallmarks experienced by people experiencing human body communication (HBC).
Rather than try to address each symptom, as it has been found that prayer helps some TIs, particularly with blocking the voice to skull tech, and this is a magick forum after all, have you tried any prayer or ritual so far on any aspect of the harassment?
Well in your other thread I and another forum member suggested these were parasites, and you should banish them. Since that’s already broken out into it’s own topic we can carry that conversation on over there, that alone will help you feel stronger and more resilient. 
They don’t need to hack you to get this into, it’s all already available online. If you don’t want this don’t do anything online: go to the libraries and read paper books. You will be on cam but the info is less specific. To hack you and let you know it happened: that’s a variant on the intimidation.
Whatever you do don’t do what it says, ever: that will make it worse and it will start asking you to do stranger and stranger things, which can only get worse you will never placate it although like a good little parasite it will pretend you can. It’s probably an AI voice anyway you’re not talking to a real person so ignore it. Easier said than done I know. Also don’t believe it: when it tells you crap about people you know, assume it’s lying to make you paranoid and isolated.
So far it sounds like plain old tech. As far as I know, their idea of “occult” really is just another manipulation effort and there’s no actual magick in it. They’re psychopaths: psychopaths don’t believe in anything spiritual at all, they are broken people that can’t connect to spirit. But they’ll use the hell out of the concept to control those who are and laugh at them for falling for it. Don’t let your philosophies become a tool against you.
Education is helpful and knowing you’re not the only one. It hasn’t escalated to housebreaking yet it sounds like, or maybe that’s old hat. This is the evolution of MK Ultra. They want you to do something that can’t be linked to them, so your main goal is not to do it. That’s winning.

The dirty looks from strangers are part of the energy weapons: they hit you with VLF (very low frequency) radiation and RF (radio frequency), getting up emotional manipulation to make you feel that, but it’s not actually anything to do with the strangers. They do want to see where you’ll break and react though, and then they’ll do that more.
Personally a good death curse against the operative group would be on my list. If you don’t have wards and shield get them up, banish and cleanse and ground daily, place an iron object under your bed where you sleep to disrupt magnetic patterns. Go camping with no tech for a week and see if it follows you there to get more info. Meditate and remote view those in charge and attack them psychically.
