There are a lot of different takes in there as to what those rules are, and people (I among them) who believe they have fallen afoul of those rules.
One of the common subjects that comes up on this site is the need for algorithmic transparency to be fair about things, and it seems most of the userbase believes in this need. So, under that light - what are the rules and the algorithm blocking people for self-promotion?
If you think posts to your own content have been blocked can you request info on this (I never have, not wanting to bother people who have a lot of work to do)?
If you believe you have been blocked unfairly then is there a review process available?
My question was of course more general, because wondering about one form of blocking naturally led me to wonder about others, but my primary concern is the blocking to one's own content.
I think the users just don't like to upvote peoples' submissions of posts they seem to have some connection to. Possibly some users think of themselves as "gatekeepers" by flagging things, but I don't see that group working on "self promotion"; they're interested in political orthodoxy.
Jeff Geerling's Pi posts were popular until he posted some himself. Now they may or may not fly, whoever posts them, even if multiple people think they're worth submitting over a week.
