@scrottie https://fedi.garden is an excellent resource for finding a new server, and it's run by the same person as FediTips.

They've curated a database of small and mid-sized servers with decent moderation policies. The site lets you look through them based on year of founding, language, region, and an array of interest/topic tags like Open Source Software, Accessibility & Disability, Gaming, LGBTQ+, Trains, Nature & Wildlife, Academics, Books, Music, Film, Amateur Radio, and many more.
