Could you make an effort to curate/reply to the engagement you get on your daily posts? It's quite a bad look that may directly translate to engagement levels dropping over time when authors who get a lot of curation completely ignore most people trying to engage.
I usually engage in all the comments made on my posts before it reaches the payout date. I don't curate some comments that I feel are made only for farming rewards.
I don't engage daily but I make sure I read all the comments and curate the deserving ones. I do immediate replies to some of the important comments like the one that I'm doing right now.
I guess I didn't scroll down long enough on your posts to notice it, my bad. Not everyone waits to reply/curate that long I suppose.
I curate and engage only based on my availability. Sometimes I do it instantly and sometimes it takes a couple of days. But I make sure I read all my comments and reply back if required or curate them.
