Also, don't put all your eggs in one basket: diversify, diversify, diversify. Make a main account, but have more on at least one other instance. Instances go down for maintenance, software gets updated, owners change moderation policies, so on. If you can't get to Lemmy through your main, use your secondary.

Personally I use lemmy.sdf.org as my secondary. It's run by a bunch of retro-enthusiast Unix nerds who more care about the functionality of the tech than anything else. No blocked communities there, and AFAIK they haven't defederated from any instance outside of ones that were hacked/compromised. That does not mean you can just go there and be a shitbird though, they do have standards.
