I am happy that a plagiarism bot like @cheetah exists. The success of any blockchain-based platform is dependent on whether the number of good actors outweigh the bad actors.
Imagine if most of the witnesses are bad actors, they don't contribute anything or there are simply no new code (e.g.) bots to help identify bad content.
Then the Steemit we know today might become "Spamit" or "Pornit".
Steemit has the potential to go far. We need more people who aim to work for the benefit of the entire community as opposed to solely personal gain.
We were once close to that Spamit level. But not sure about now, because I rarely scroll the created page nor the trending page. My feed is still good :)
After all, it's a blockchain. We are the ones who control it.
