Using Signal with disappearing messages set to a really short time is probably the closest thing you can get. You can use a VOIP number from Cloaked behind a VPN to sign up anonymously.
For security reasons GrapheneOS doesn’t allow the modification of system files. You can achieve the same thing with DNS though. Either self-host a Pi-Hole or AdGuard Home, or use something like NextDNS.
I wouldn’t recommend a Pixel older than the Pixel 6 as these will soon be EOL.
Signal is finally delivering the stuff we have all been waiting for. First, they implemented post quantum cryptography in the protocol in September, then we got message editing, and now we will finally get usernames. Awesome!
Some solutions:
Yes, FFUpdater is an awesome tool.
Just use Mull. Don’t support Google’s monopoly on browser rendering engines by using Chromium based browsers.
Definitely don’t go to fmhy.net and definitly don’t join the !piracy@lemmy.dbzer0.com community. Also don’t visit torrentgalaxy.to, 1337x.to or solidtorrents.to. You probably also wouldn’t want to check out rutracker.org or therarbg.com.
I remember using this (cheating a little bit with VPNs and proxies so I could claim the rewards like 20 times every day, because they are separate in every country) to get some Xbox giftcards
I also had ~15 Microsoft accounts and I put them all in a Microsoft family so I could transfer points from one account to another, it was really fun lol
