I have dealt with this person for a while now, and the police advised me to change my phone number, which I did, because this person has been spamming my phone, random calls, texts, harassment, and bullying, etc.
So I changed it, and about a week later, it began again. This should not be possible at all, can someone explain?
I only shared this new number with family members, and switched out from online accounts registration. I made sure to check every single accounts by the way for signs of breach of security, nothing at all, same IP address (mine), and same devices (mine). So how did this person find my new number?
I suspected maybe my PC is infected with a RAT of some sort, so I decided to install linux, and do my private stuff and changing phone number on the system, so whatever infection windows pc had, the person won't see my new number when I change it on accounts. I don't think this worked or helped.
