My verdict: While there is nothing wrong with the idea of the app, sharing 15 second videos, there are some issues with how it is being used. When you sign up the privacy setting is set to public. If you change it to private you will avoid 40 year old men sending inappropriate comments. You can also turn off the comments facility, otherwise it's just another avenue for trolls to do what they do. Any platform that is used by young people attracts pedophiles. One scantily clad girl had the message on her screen, "I'm fifteen, if you're over 18 and tell me I'm hot, that's creepy." You can't actually delete your account - you have to provide your phone number to the app so they can send you a code to delete your account. Finally, you can waste a lot of time on Tik Tok so maybe set a timer.
