please help

Hello. I am a woman new to this site. My ex is a high up programmer and he is targeting my email Facebook and more. His name is Christopher Michael of the company samsung. Can anyone please help block him or something? I have also sent a complaint to the fbi but he is still making fraud pages trying to scam me out of my burning man grant funds. Any help would be greatly appreciated. He has done this for several years and is ruining my life. I can get a job because of him and I’m starting to starve. Please someone help before he causes a death. I have seen him do this to other women and think it is funny. I assure you it is not and very scary.
