There is a section on Fedi.Garden where you can browse hand-curated Fediverse servers by the year they were founded:
https://fedi.garden/servers-sorted-by-founding-year
This may help when trying to find a server with a good track record.
Also, no matter how old or new they are, all of the servers listed on Fedi.Garden are compliant with the rules at https://fedi.garden/about-this-site
