10 years ago, I launched a small modification to a social network I was running at the time - you could only post once per day. The quality of the content went through the roof, but it turned the product into more something like Medium. It had some upsides, but also some downsides. It was amazing to see how such a simple change can dramatically alter the nature of the product.
This to me is the equivalent to the war on drugs. If you limit someone's ability on your platform, they will find a different platform. Until you squash the need/desire, those with the need/desire will find a solution.
