They either need to make a rule denying posts about storage server, or start enforcing it fairly.

If they had a rule like that, I could accept it, as selfhosting to me implies more of running a service on the internet rather than a “simple” or “standard” storage server.

That would be better but storage is a fundamental part of self-hosting, given that commonly used services need significant storage (e.g. Immich) and storage redundancy is vital to the reliability of self-hosting these srvices. And it’s not just storage either. The compute hardware also has a fairy tight connection to what’s being self-hosted. E.g. GPU, RAM, has significant bearing on the ability to self-host LLMs. Because these topics are interlinked, the knowledge exists in this community’s members’ minds. Trying to separate it means these same people have to figure out another place to gather to talk about that subsection of self-hosting. I’m not aware of such a community and historically (here since 2023) /c/selfhost has been the place for it.
