Of course copyright infringement isn't okay. And people who steal other people's content, should be flagged.
But the problem here, is the finality of the block-chain. Ones posts are stored in a blog and pushed into the network. They can't be removed. So that's going to cause problems in the future.
Normally with copyright infringement, someone can do a so called 'take-down notice' and claim a compensation.
But here, the published content can only be deleted for a few short amount of time. And their isn't even a legal entity to go to.
