Hey guys I am confused about how privacy friendly are lemmy and matrix I would love if someone can answer these questions :- 1.) some websites state that lemmy prefers you to have one user server (that is 1 server with only 1 user ) , but somewhere else i read that you need to whitelisted by servers to allow you to post on their community , 2.)Matrix is bad as default but you can self host it , but for self hosting do you need to get a domain name a vps and the hassle of managing it , isnt there any .onion address that i can use 3.) can i use duckdns or no-ip to get a subdomain and then host matrix /lemmy server there , how safe /applicable is that

Can someone pls link to any sources on how we can maybe support fediverse by translation or coding (if possible) as well , and make them as efficient as their other counterpart (like matrix to discord , since i heard matrix is preety bloated)
