AITA for doxxing my bsf’s perverted X

Okay, backstory on this I (19F) have been friends with this girl (18F)-calling her Isla, the s is silent, she said I could post this to you and gave me her “name”-has been dating this guy named Isaiah (22M) for I’m not sure how long. (Also his real name is Isaiah, I don’t feel like his privilege to his privacy should matter because well, he saved a few pictures from my friend and blocked her)

She texted me a few hours ago crying, because her ex boyfriend blocked her after she sent him some pictures-which he saved before blocking her.

I added him.I was disgusted in him, saying a few choice words to him, I called him a pervert, a pedophile, commented-angrily, because it looked down right ugly and awful-on his neck beard, saying he looked like he was in a mugshot and that he should no longer live on this Earth, he read my messages and blocked me, which I knew was going to happen because, well, he was a coward in my eyes.

I’m very protective when it comes to my friend. I live about 50ish miles away from him(he’s from Lacey’s Spring). So I did what any normal ticked off coming of adult teenager would do, I doxxed him on my Snapchat story. I know I probably went over a boundary with that but I felt like he needed to posted about.

He hurt my bestie. So AITA?

(Also Charlotte I LOVE your videos. Especially the editing I hope you have a good day)
