Name changed for this as my friend knows my username.
DS is 15, my ex sent me a message last night telling me his DD found DS’ tiktok account and he's got over 100k followers. I has a look and it's about 117k 
. I knew he had tiktok but he said his account was private and only his friends followed him which isn't true! There's lots of girls putting heart eye emojis in the comments of his posts and one comment I've seen is inappropriate! A woman commented ‘i hope you're 18+’ he replied back that he's 15 and she replied ‘thats a shame, I'm 19’.
I'm not sure what to do about this, I've not spoken to DS yet. I'm also annoyed that he lied about his account being on private but I'm also uncomfortable at the comments!
