Niall sent similar furry NSFW to me (I was 18 at the time so no issue there) in probably early 2017. Me, Ivory and Niall were all in and out of the same friend group and it does not shock me that the same content was sent to others. It was known to all of us that Ivory was 15. https://twitter.com/IIovebird/status/1322337324601102338

No interest at all in talking about this with anyone, I'm not in anyway harmed with what he did (although I never sent anything back or anything like that) and all the accounts are deleted, you can chase proof that we were friends if you like, its around. Ivory isn't lying though

anything else you need please go and watch the video where ivory shows his DMs with Niall's current partner Ida (who I was also friends with back in 2017) where she admits Niall did this. If you cant find it then you aren't trying to
