Please help! Domestic violence survivor and I feel like cops aren’t helping. Am I just crazy?

I got a restraining order on my kids' dad last year because he choked me and then threatened to kidnap me and torture my body until I died. Since then, he's been (imo) manipulating the system to stalk me without getting in trouble. He uses third party people and makes fake accounts. He even had a guy he worked with work for him to try to get me into a hotel room. After that, he had one of friends (I didn't know it was his friend) add me on Facebook and act interested in being with me for information. I went back to a job I had when we were together and I really think he found out somehow because I got a request from someone using the name of a dude he was jealous of. But I didn't realize it was fake so I accepted it. He started asking questions about himself. I blocked it. Since then, he's made many accounts to do weird shit like this. Then he took a break for a couple months. Then the other day, I started getting weird requests again. I ignored it but the messages were still going through. It was from different accounts asking to be unblocked and for sex. I was trying to see if he would admit it was him so that after a YEAR of this, he would stop and/or get arrested. I even tried to say that I wouldn’t report it if he just tells me. But he wouldn’t. I tried to contact cops anyways and at first they said they would investigate it. But then said to just keep blocking it and that it’s not a big deal. But it’s been a year and like 8 accounts. I’m worried that he will instead just do something even worse, something that heavily interferes with my personal life (he’s prone to causing scenes, public humiliation), and I don’t want that. They said the order is more for when/if I see him in person, but I think with how heavy of a risk to me he is, by that point it would be too late. I feel like no one in real life understands.
