Just out of interest, there must be a separation between content posts and comments. Because when you post content you have the option of how to split reward and if you automatically upvote yourself or not. But we do not have this for comments. So would it be that hard to change the rules and make a larger separation between comments and content? I don't mind people upvoting their content posts, or using rando whale etc ... on their content, especially if it is quality content. But I do not agree with being able to vote or use randowhale etc.. on your own comments. Couldn't we make it a strict rule of no upvoting your own comments but still able to do it for content. Apart from that I do agree with upvoting comments and before the hardfork I used to upvote any comments on my posts, but do not at all now, unless its an amazing comment.
Thanks for your post, I like your ideas of how to help fix the problem we now face after the last hardfork, and totally agree that something needs to be done!!
