With the amount of ads I see for things like NordVPN or PIA openly advertising bypassing geo blocking I doubt many people haven't heard of them. (Those who haven't will soon hear about them from friends)
They will delete it if they get a DMCA takedown request, as required to avoid liability under US law. They don't however proactively look for copywriten content. As long as the music owner doesn't care or doesn't notice it will be fine.
Similar to a modern 64 bit computer, my computer actually has a 512 bit wide ALU for SIMD, basically it lets you do the same operation on multiple numbers simultaneously.
For alerts I just have the server directly send email over SMTP to my address, no service needed. You could implement DKIM with such a setup if you wanted to.
No, if you want to see a community more, subscribe to it so it shows up in your subscribe feed. The "Hot" ranking is only based on the age of a post and the score, "Active" is similar but using the time of the last comment instead.
The feeds are "All", including every post on Lemmy, "Local", including only posts to your instance's communities, and "Subscribed" showing subscribed (joined) communities.
You can connect to most instances over Tor, but hosting a server over a Tor hidden service would cause problems as it can't be connected to by stock servers. (If you convince others to run other Tor hidden service instances, they could probably federate with each other)
What consolidation? lemmy.world and Lemmy.ml are by far the largest instances, and are going down from the load. Lemmy was designed to be resilient against a single server going down, but if everyone is on a single server, and that server goes down, everyone can use Lemmy.
There is a lot of other fun stuff you can do with RF, some people even found a way to spy on keystrokes by sending microwaves at an unmodified PS/2 keyboard cable.
