Firstly, in no way are YBU not allowing an 8 year old on social media.
Age - recommendations exist for a reason, and it is insanity allowing kids that age to use live-streaming apps, Instagram and the like. They really have no concept what is safe or what to reveal, and kids are mean on social media.
Keep her away from it till she meets the recommended ages - which, to be honest; are a pretty low bar for some apps. I did this to my sons and they both survived and now treat social media very carefully.
Secondly, TikTok , which used to be Musical.ly is a clusterfuck of epic proportions.
It has been fined in the USA with the largest EVER civil suit for illegally mining and storing the data of children without the consent of their parents. The developers captured names , emails, phone numbers, images, and the personal photos posted by said children. And kept them in perpetuity- till they lost their law suit under COPA - ( US children's privacy act)
It uses facial recognition software, and the data is stored offshore in China where the laws re privacy are in no way comparable, nor is the right to on sell third-party data.
They were also aware that there were numerous children using the app well under the 13+ recommendation due to complaints from parents re grooming, and request for explicit acts from kids from older users but did not view this as an issue or take any action till forced to.
India has also had a run in with TiKTok re content ,and I think there is another lawsuit against them starting in the UK for similar reasons.
Anyone, can watch without an account and if you spent at least fifteen minutes flipping though the clips, I guarantee you will find explicit language, explicit gestures, references to drinking and drug taking. You cannot police this. It is not appropriate for anyone under about 14/15/16.
But the cracker for me with this app, is this.
When the US insisted the age gate be enforced, TikTok shut down - without warning all of the accounts of individuals under 13 on the app. A large bunch of ADULTS took to Twitter to complain about being locked out of their TikTok account...because they had been pretending to be a pre-teen and couldn't any longer.
Rather than boot these users into the stratosphere for being creepers of the highest order, TikTok offered to sign them up again if they'd made a mistake with their birthdate (!!!), once they sent this data mining behemoth, certified copies of personal ID.
Individuals were trying to do this , because then the dialogue on Twitter changed to also being locked out of the TikTok website , and therefore making them unable to hand over their personal ID's.
It was a scary mess, and this all took place this year.
So regardless of whether this app has/ is developing an under 13 section, simply for its record with data mining and its pitiful response to all those folk who outed themselves on Twitter who had been pretending to be kids to befriend kids....I wouldn't let a child use it. It's up there as one of the most unsafe apps around for multiple reasons.
Sorry for the rant, I hate this app. A lot.
