Less than a thousand when I considered it in the past couple years, but not worth it for me due to overrated data durability. Found we need home vinyl record etching machines if we want something as good at shelf stability as these tapes are sometimes proclaimed to be.
Not bad for pure storage density though
Not that I know of.
An easier build would be using a pre-approved list of sites known to not be ad-driven. Like, right now if you limited your search to piefed or nostr then that might avoid ads, but instead of doing it one at a time, it would be good to have a way to search a list of known sources like that all at once. This would be limited to the manually added search sources, but it’s really hard to program a system to automatically find all the ad-free sources out there
