If communications are generally encrypted then that absolutely is surprising. In that example all the clients could be counting the emoji bs or whatever individually without any server even being aware of the message content.
NFT are just like tweets. An NFT of a torrent is the same thing as a tweet linking to a torrent, just that in this case the tweet is stored in a blockchain and people can buy it.
I understand what NFTs are, but torrents are ephemeral and recreatable and frequently replaced even for the same source data, more akin to indices. Proving you had a copy in the past or traded for said proof conveys nothing if no seeders exist anymore, and abandonment rates are huge outside of archival communities.
Other than the mystery and the joke what's the meaning of a NFT for the URL of a deleted tweet?
If you participate in facebook etc apps and services at all they have far more insidious and effective tracking and NAT isn't hiding you at all. Additionally the idea that it is granting you any measure of privacy is only true if you're behind a giant translation block with tens of thousands of unrelated people and a broad enough public range that connection correlation becomes impractical, compressing a single family or roommates behind a single public IP that changes maybe every few weeks accomplishes very little if anything.
If you need anonymity that much for whatever purpose, depending on v4 NAT is dangerous at best and you should be looking into anonymous proxies or VPN providers (that also mask ipv6), Onion routing, etc.
There's no reason you couldn't, but distance is not the only source of latency, so you're unlikely to find an existing case of someone doing that intentionally.
Easy enough to whitelist geo-ip matches or large net block ranges for a similar result.
When affluent and educated societies worldwide show declining birthrates and increasing age at reproduction, it can be taken as a strong indicator of women's and family's preferences for fulfilling lives at demographic scale.
Taiwan was, and is to a lesser degree these days, also highly patronistic in terms of you needing to know people to get that kind of government support. That kind of corruption was why the locals were protesting and organizing against the KMT in 1947 and still echoes today in a wide investment gap between northern and southern Taiwan.
Morris Chang may be a great guy but he was directly recruited by an authoritarian government that was still operating under martial law, and that absolutely was not an option available to most Taiwanese.
