I blocked someone because they've repeatedly made me and my friend uncomfortable. AITAH? (TW: Mentions of sexual activities and provocative pictures)

I (15m) was talking to an old friend of mine, "Kayla"(14, trans mtf) and she told me that she masturbates to pictures and thoughts of me. I was telling my current friend about it, "Jamie"(14) about it, and they mention that Kayla texted them multiple pictures of her in various poses, and you could tell that they were visibly disgusted and uncomfortable. They show me the photos, and you can tell that it's not that. I blocked Kayla after that, and she's been texting me from various Insta accounts and phone numbers. I've tried to tell her countless times to leave both Jamie and I alone, and I've blocked 2-3 different accounts & numbers of hers. Was I wrong to do it ?
