I took a quick peek at your profile @cherepin, and my guess is that no one sees your content because you barely interact with anyone else. And when you do, more often than not, you're complaining that no one "sees" your content (which most people would interpret to be a complaint about the lack of upvotes).

You're also only posting in the general "GEMS" community, instead of specific communities related to your content (where it would have a higher chance of being seen).

Try joining communities you find interesting, and genuinely engage with people under their posts (not just in a "great post" sort of way), and I'm sure you'll develop a following soon.
