The graphics would be called chibis, IMO (or デフォルメ if you wanna be fancy) and IDK about developers, but perhaps weaboos/weebs would be the general term

+1 I guess I’m old as well. The presentation makes it seem like I should recognize them, but obviously I don’t. Would love an explanation.

This is giving a big anime-enthusiast and possibly furry community vibe, it's really pretty separate culturally than just being a developer. For people who really are into it, it becomes a fetish... and no judgement for things that happen between consenting adults but... it can seem pretty odd from the outside. But it can also be entirely innocent, nothing wrong with liking certain art styles.

So if you don't understand these things best not to copy them because you could unintentionally be sending some pretty strong signals.

It's also somewhat in the style of the Manga Guides, which are fantastic and an entirely different way to make some of these things accessible.

It's both anime/weeb and furry art styles. Usually these are two groups don't really have anything to do with each other but the author is just part of both.

Which doesn't strictly have anything to do with developers either other than the author being part of all three.

There are but they all get you banned.

Disturbing that imagery of children take up so much mindspace that they use them as their avatar. Half of these people have CP on their computer, guaranteed.
