> when I attempted to post my things, I get told that this content is not welcome on the site. Why my content is not welcome and other people's self-promotional articles are I don't quite understand, but it is obvious they don't need me on the website.
I feel the same. I spent a fair bit of time on the site, including posting ~600 articles and commenting. Some of my posts got a fair bit of upvotes. I got a couple of warnings when I posted my own content, even though it was 5-10% of my posts. Super frustrating, so I told the moderator I wasn't going to participate any more. And I haven't. Their site, their rules, but I don't have to spend my time there.
Weird because primarily submitting one's own stuff seems to be pretty common there. Random example from a user currently on the front page: https://lobste.rs/~rednafi/stories
And that is not the only one on the front page right now that's submitting mostly their own stuff.
To nitpick: that's not a comment from a mod. Posts speaking from a position of mod will have [sysop] next to the title. It's part of a "hats system", which more generally allows people to speak as representative of something. IE if /u/johncheng was a Rust core dev, they can post whatever they want as John Cheng, but also write posts as [core dev] to say they're speaking as part of the core team.
It's a neat system but doesn't see much use in practice, aside from the occasional [sysop] warning.
Personally I don't see a problem with someone posting their own content, especially with voting based ranking. As long as it's not spam and is on-topic for the site, the origin shouldn't really matter. Compared with someone who posts only New York Times articles, I'd rather see someone post their blog entries.
