Certain Lemmy instances are not much different from the kindergartens over on Reddit. The same type of kids take over mod roles, forcing everyone to follow their ideology - or else, banned!
I would fully support the option on Lemmy to block or ban entire instances that suppress free expression or prevent challenging false claims and narratives. I would also fully support the possibility to complain about a mod and even demand his removal as moderator with the possibility of banning even the mod. So, not only top-down, but also bottom-up - but so think the letter is not possible in Lemmy. Only instances can be closed.
I would say that Arch is not the best distro to learn the ins and outs of Linux. Arch is comparable to Void in that both are rolling-release distributions and require comfort with the command line.
Gentoo goes a step further by allowing you to tweak CPU-specific and software compile-time options before building packages from source. Then you have PLD Linux, whose installation process demands a strong understanding of the system and its internals.
A step further down is CRUX, which leaves you with the bare essentials - essentially just the kernel. You need to manage repositories yourself to a significant extent.
Finally, we arrive at Linux From Scratch (LFS), which is somewhat similar to CRUX, but with an even more hands-on approach. With LFS, you must manually install virtually everything, including the toolchain, libraries, and basic utilities.
So, from Arch to LFS, there's still a huge gap in terms of how deeply you engage with the system.
Finally, what does it really mean to “learn Linux”? You can learn Linux with any distro, but when you are using a distro, you are mostly just learning that particular distro.
