Don't worry about it. It's just scare tactics and to distract you into paying attention to their bullshit. And to cause you confusion and paranoia, also to drive you insane. Just ignore it, while making note of it and up your opsec to secure your shit. Don't tell others, it's purpose is also to drive you to tell others so as to make people think you're crazy and further isolate you. I mean you can fun with them, flip them off, tell them to fuck off you don't care, or better yet give 'em a friendly wave now and then.
