I do think that there is more spam in the comments section than post related!
I could life with limiting the number of posts a day to max 4 or 5!
They claim that a post or comment is only worth something to the blockchain when the value should be high enough. Like always I strongly disagree to this. A post with a payout below the threshold level but with lots of interaction has more value than some meme, which gets upvoted to the moon or by selfvoting!
