I think this is common sense: Peter Taradash, a/k/a/ "Grandpa" says: If someone is going to break the law with threats, harassment, extortion/blackmail attempts, they risk exposure. Tor, Proton or the Dark Web, etc. can't offer 100% anonymity. Some of the comments on this article offer additional ways to cover your tracks & gain enhanced privacy, but the best advice is: stay low profile. Don't do stuff to ruffle the feathers of the "authorities" with anything you do or post. Consider everything you do on the Internet as a "public record" that will lead the cops right to where you sleep. The ‘enemy’ can open & read all your online stuff. They can tap phone conversations or open snail-mail—with a court ordered search warrant. .. The thing to remember is that "the authorities" can open and read everything ONLY IF THEY CHOOSE TO. Their manpower limits mean they can only choose to seriously monitor only .001% of all traffic. Thus, ordinary blokes like us won't usually be surveyed unless we are "lawbreakers" or have dangerous 'hot' friends. Obviously, don't use words that will set off any alarms.
