I recommend not using TikTok for any reason. Using it turns you into livestock. It's a disturbing app which, even since it was Musical.ly, has existed for the main purpose of monetizing underage girls.
Even if that's not what you follow, that's the base of the platform. The platform is mainly used by minors, and all of the trends are created by minors. The app serves to sexualize young girls, it rewards them for promiscuity. It devalues their beauty because they show it all for their anonymous, likely adult followers. It's basically a big anonymous grooming movement.
If you ignore this truth of the platform, it's still just taking your EXTREMELY valuable attention, and wasting it, to give time to collect and sell your valuable user data. It's highly likely that data is being illegally accessed.
Shorts are bad for your mind. They are bad for your attention. They teach you to have ADHD. We should only absorb media in long format. TikTok is making ignorant experts in every arena. It is not good for anyone. The fact that the app is psychological terrorism combined with the fact that they are collecting unprecedented amounts of user data should be more than enough to convince any adult to avoid the platform like the plague. Or you can wonder why you can't stare at nothing for hours on end. Whatever you want to look at on TikTok, read about it. If it's girls, give up on that. Lose that which distracts you.
Edit, Call me a conspiracy theorist: musical.ly was dying before Chinese corporations connected to the CCP pumped billions into it. I'm 90% sure that TikTok is a psyop (psychological operation) to spread "tics". It's pretty blatant, all of this. It serves to weaken our men, divide our people, and enable the eventual invasion of the US mainland. For this reason, I will never give into the general weakness I sense within society. I will continue the tradition of manhood at all cost. I'm 24 btw, I was 12 when Instagram was created. I'm not just an old doubter. Social media is detrimental to everything if it's designed to cause addiction.
Edit 2: I understand this in absolutely no way answers what you asked, and I completely pontificated my opinions. For this I apologize. I feel that this information is essential to save our society before it collapses. Some evil dictators want power at all cost, they will sacrifice billions of humans. I will preserve the natural order at all cost, no weak dictator shall dictate over us. Abundance is our right, nature provides infinite abundance. Scarcity is artificial. Do not be controlled by anything but your own mind and heart.
