Not everyone wants their internet platform overrun by trolls.
But what about those of us who DO?
There should be a configuration setting - not force everyone to live in a troll-free environment.
What I mean is that if you have a "product" on the internet, like instagram or twitter or google or facebook, and you are trying to make lots of money from it, then you may not want it overrun by trolls.
If you want to create a product or platform on the internet and have it overrun by trolls, then you would still be free to do so.
