All the tools designed to discover different communities seem to disagree on what the subscriber counts and activity levels are. The Worldpolitics bin on lemmy.ml is listed as 2.5K some places, 10K some places, but when you go there it has almost no posts despite being the same size as the News bin on beehaw. It's all very odd, hard to know what to "trust" when it comes to finding new, active bins.
The downtime is causing an issue with posting content from other instances - I've seen this a handful of times from kbin. I post something to a lemmy.world community, and kbin thinks it's there, but lemmy.world doesn't see it. But, the delete request seems to need to go through lemmy.world, which doesn't agree that the content exists. So my profile is filled with posts people on kbin can see, but no one else can, and I can't delete them. Is there any kind of catch-up mechanic for instances to try to agree on what content should be present if content was altered during downtime? I can see this becoming a lot more confusing as people look at a community from multiple different instances and see different content, not realizing this is unintended behavior.
The biggest misconception I've seen on Reddit and elsewhere is that you need an account on every single instance if you want to interact with content on that instance, and it's not supposed to be true but while this bug continues, it kind of is true.
