Thank you for sharing this eclectic list! I really appreciate the time that must have gone into this.
I have noticed that some of the links are rather specific (like the longer Williams Sonoma ones). Do you plan to periodically check this for dead links?
I generally agree, but I do somewhat agree with Beehaw’s decision as long as it is actually temporary. They say that they just don’t have the moderation tools required to handle the influx of low quality posts from those instances. Considering the ballooning of active users on all 3 of those instances (Beehaw, lemmy.world, and sh.itjust.works) I could definitely believe that. Paring down the amount of potentially rule breaking posts until you have the tools necessary makes sense.
The idea that every instance can just cut ties for whatever reason, though, is scary for the reasons you have outlined.
