I think you have a hard time managing the replies in part because you get so many millions sometimes. And I believe many of those may be bots, given I saw on the competition one you did on AI and Blockchain had a load of bot comments.

But really, Comment and Reply management system on Steemit is one of the few things that really set Steemit apart from all the other social media I know and use, such as Facebook, Twitter, YouTube, Pinterest, Yours, and especially Minds. But Minds is gaining fast and I'm sure has nearly doubled the membership of Steemit as fast as they are growing, if not more. For example Minds started to see some issues with bots gaming the system, like Steemit, and quickly changed the algorithm within a few days to take away all incentive. I have seen that and so many other debates rage on Steemit of all the problems they have for more than a year and they have yet to fix any of them. Yeah, maybe they lowered the power down system to 13 weeks except 5 steem, but that's still ponzi scheme scam territory and the number one reason I am not posting now for nearly a month.

It's simple as hell to at least find replies form specific people on Steemit. You simply go down the list and check which one. When I told you I had commented, I even told you how many days before it was, so all you had to do was go though to that period past and look for my username.
