Demand on the tech companies to act against fake accounts

There are so many fake accounts on the internet Twitter, Facebook , Instagram , TikTok and Google. These accounts scam and steal from people, but the tech companies will not do anything because it goes against their policy of having so many accounts, the more accounts the more they can earn from advertisers. The accounts the fake accounts follow won't do anything because they would lose 50% of their followers and that would be devastating.
