I ran mine for a bit and it’s a resource hog, fragile, and images are a constant problem because the cache just keeps growing and growing so either you keep a limited timeframe of user images or you pay for storage elsewhere.
I was the only user so I didn’t have to deal with moderation, but what finally spooked me was the possibility of someone posting something illegal and it propagating over to my server. That was why I stopped hosting my Lemmy server, too.
Upvoted for PBS alone. Incremental backups that are rock solid mean you can completely brick your server and have it back to normal in minutes
