Is this normal?

Is it normal for social media to have accounts offering free [PHONE]? Example: On Facebook, some time ago, I kept seeing ads for [PHONE] links that then took you to an app on the Play Store to download and watch free [PHONE] videos. The same happens on Telegram and TikTok where a bot appears in an ad and offers photos in exchange for a $1 subscription. Then the bots kept sending videos of [PHONE] from India and the United States. Worse was Facebook, where I remember there was an account, I think called Neuro, that uploaded adult videos and a link full of viruses. My question is: Is this normal on social media?
