I’m not looking for someone to hack anything for me. Just looking for info.

So basically I have someone who is harrassing me on social media by making accounts and spreading a bunch of bullshit about me and my past. Some true but most is bullshit. If it was just me then I would just brush it off but they are now involving others that have nothing to do with anything. Every time one account goes down another goes up. I’m no hacker but willing to learn. I guess my question is, how hard would it be for a newb to figure out who is behind these accounts? And for those asking I’ve contacted the authorities and they say that because I report the accounts and they get taken down they cant do anything even though a new one pops up a few days later posting the same stuff. I know it’s a long shot but thanks for reading.
