weird toxic ex bf vent ??

My ex bf has been sending pics of all of his ex-gfs (including me) in a incel discord server, basically flexing to all these losers how he's gotten girls.
its acc disgusting because i found out he had like some 'plan' to befriend me, date me then have sex with me. i was love bombed bc i had no friends and reading all the chats makes me sick but i cant stop reading out of curiosity. He also mentioned how paying for our dates was a waste of money. He also posts pics of himself begging for validation and it is so cringe. I could just get revenge and expose him in the server and embarrass him but i choose not to.
i just feel SO mad he's speaking about me in there and i want him to stop sending my face! He even wrote "do u wanna know how i got this one" n sent my face. like treating me like an object n i was just a face to him??!! Like he has a massive ego from manipulating girls but rly he's just a loser and i regret being nice to him even after the breakup!!
im just glad im not with him anymore, thats all im venting about, but seriously he's the worst guy ive ever been with and it sickens me how i let this happen and didn't see his intentions. it just makes me feel like im unable to trust anyone in the future as all my ex-bfs have been massive idiots.
i dont know if i should break no-contact n tell him about this and tell him to stop sending my pics + talking abt me or should I just leave it alone???n also i check the chats logs like everyday and idk how to stop....bc its srsly making me so angry.

Read this and I am sure you will see that it is like Harassment or Stalking. Laying an Information at Magistrates Court is easy, I have done it twice and the Magistrates are infact very helpful if you do it yourself. Really it is simple (like me,lol).

what does this even do may i ask??
