Seems like we'll be having a reputation system to fight of spam/bots.
I was wondering what the hell his solution for that would be. The obvious answer is being required to burn a fee to post. His solution is far too complex and can have innocent users gamed or their speech suppressed imo...
The answer might not be as obvious as you think:

Just prune the blockchain from comments/blogpost with less then x upvotes or something similar.
Imo you want to only keep the things of interest anyway.
Why would comments (and votes if you are referring to reducing data bloat) get pruned. Everything that is published is to be retained forever. There is important information in comments as well.
Who will decide which comments are important and which can be deleted. You come full circle back to the censorship problem again.
