Would it bother you if your anonymity on Reddit was compromised?

That sounds like she's maybe spying on you, like spyware on your computer or phone or a spycam in your house? Cyber spy is more likely. I'd be doing full reinstalls of all computers and phones and changing passwords to emails and all social media accounts. Actually if she just had your email password she could see what accounts you had created. Still, I'd definitely do a thorough clear just in case. If it's what it sounds like, she could really fuck your life up if she chose. Think how many important services will send a password reset link to your email? Think how she could see you succeed with, for instance, a great job offer, get jealous and just delete the email before you see it? I'm not normally one for dramatic explanations of weird stuff on computers but this sounds very suspicious. But you can msg me if you want to talk it through in more detail, I work with computers and am well informed about cyber security.
