Hi, my DDs are asking once again for tiktok and I'm quite inclined to say NO, but I've seen there's a built-in parental control in the app and I didn't tested it... do you know how it works? Is it totally trustworthy? I mean does it block for sure all the inappropriate videos, or what is displayed is still all up to their algorithm pushing hot, stupid or unethical videos in the name of more clicks?
