What community you're in is right in the URL and can be found at minimum twice in the sidebar. Just look for @[sub]@[instance], or the previous with @[username] in front of it.

Tankie refers to the when Russia sent tanks in Hungary to stop them from setting up a communist government that didn't follow their particular communist ideology.
That's a good point, and I'm sure that would certainly be a problem with PageRank and similar ranking algorithms, but I wouldn't be entirely surprised if Google and other SEs have intelligently crafted a pre-processor that translates links like "kbin.social/m/[email protected]/t/34817/Is-Lemmy-Indexable" to the Original-Instance-Link (OIL, lurking Google devs feel free to steal this acronym) "https://lemmy.world/post/189226" so that relevant algorithms properly reflect the 'true' ranking of the information itself rather than the particular instance's... instance of it.
OStatus and Pump.io have been around for a while so SEs may (should) have already identified this problem and addressed it unless they've decided it's not important, not in-line with how their rankings are intended to work, or simply not easily solvable in some cases like I previously assumed. As Bjarne Stroustrup would say, "If you think it's simple, then you have misunderstood the problem."
It's certainly archivable; all one must do is look at the 'robots.txt' (a file that websites use to let nice search engines know which pages they shouldn't index) associated with the domain to find out what it permits to be indexed. Lemmy.world's robots.txt only disallows pages associated with instance/account creation, user settings, and administrator/authorized interaction.
So everything relevant to how reddit appears on Google is possible for Lemmy, the only difference is that Lemmy's associated PageRank (and other ranking scores) are considerable lower than reddit's. This should change with time, especially when more niche and specialized communities take hold.
It's not really a limitation of the software, it's all up to each instance to decided how they handle things. Instance admins can code in a banner as you describe and they can make defederation transparent such as how Beehaw lists all linked and blocked instances. Every instance can do this, they just have to choose to implement it.
Yep, spirituality is an emergent property with respect to imagination and a lack of omniscience; if something happens that is not explainable by an individual's knowledge they'll find it easy to come up with an imagined explanation.
This is why earlier religions explained things like the seasons, weather, earthquakes, volcanos, stars, etc through imagined gods while those same, evolved, religions don't attempt to do so anymore. We understand them scientifically now.
