A couple of weeks ago, I brought up a problem recently. The problem was this one person, kept trying to contact me after an argument. He harassed me in the past, and keeps trying to add me. I've blocked him, changed my settings, and messaged him to leave me alone, but it continues. I made it so I cannot receive messages outside of my friends list, but I can still receive friend requests. I really need help. He's trying to add my friends to get to me, and he's done enough already. Any suggestions?
