This reminds me of:
What happens in a copyright infringement scenario?In reality; anyone would be able to make a complaint with as much as text as they want.
This isn't reality. This is pure theory.
Media could try to suppress the statements made in the public ledger, but anyone who downloads the entire ledger would have access to read all complaints.
Here comes free speech.
Has anyone gave this any thought?
Yes, it's undoubtedly expensive to save much text in the Bitcoin block chain and extremely difficult to extract it. It's mainly for transacting bitcoins and even that is tackled with second layer solutions. Can you explain me why would you want to state your complain publicly?
