It's a great idea. The real bonus would be micropayments for the times comments are kept back - users can pay their way over the block. Stacker News already requires MP to post (and users earn as well) https://stacker.news (crypto community) - just make those optional. Actually with Stacker News it isn't always mandatory:

"You don't need bitcoin to get started. You can create your bio for free (with limited visibility) and earn Cowboy Credits (CCs) from zaps to cover fees. Posts and comments incur a small fee to prevent spam and to encourage quality contributions. Many stackers earn enough from their posts and comments to continue posting on the site indefinitely without ever buying CCs with sats." https://stacker.news/faq

After that turn it into a Wordpress plugin. Could also launch a token at the same time.
