If you think this post would be better suited in a different community, please let me know.
Topics could include (this list is not intending to be exhaustive — if you think something is relevant, then please don’t hesitate to share it):
- Moderation
- Handling of illegal content
- Server structure (system requirements, configs, layouts, etc.)
- Community transparency/communication
- Server maintenance (updates, scaling, etc.)
It would depend completely on how many users you let in and what kind of things they’ll be doing. Some users are super heavy with uploading images, some users aren’t.
I haven’t read the docs in a long time, but perhaps you could restrict image uploading or something. Nothing you can do about unbounded DB growth without expiring content though.
