Boards that have rules against self-promotion are a sign that they're centered around one or a group of influencers, or that the board intends to promote whoever is running it, rather than being a real social community with mutual interests where people actually learn to know one another.

huh? got an example? I've been to quite a few topical FOSS oriented subs and i'm happy for the no self-promotion rules.

It's usually a bunch of people making an inferior version of neofetch or whatever basic tool is well known to the community.
