Is anyone weirded out with the amount of young girls on Tiktoc?

Every day I see someone new on my FYP saying “hi I’m “so n so” I’m 9/10/11/12 and I like doing “this” (painting nails/dancing/singing” I feel like parents THINK only followers can see their pages but they can easily set them to public! I personally am not comfortable with even pics of 7 and 2 yo online.. let alone whole videos with ways to contact! The other day I caught my 7y/o son making Tiktoc dances with the neighbors girl who is like 8.. it was harmless obviously, they were in the driveway but I don’t know her mom like that.. I don’t know if she checks this stuff.. and perverts look for kids like this!

When I was a preteen with AOL my parents monitored everything.. not exactly my conversations but who I was speaking to.. how can we be so sure now with all of these apps.. idk I just don’t think kids that young should be on that kind of site

Please tell me if I’m crazy! Like anyone could see that and just contact them! Creeps me the hell out
