I guess the idea is (make of that what you want):

• Usenet is not illegal by itself (but well, same goes for torrenting)
• As long as law enforcement doesn’t get its hands on the server it can’t tell what you download, as long as you use TLS (no VPN required, but doesn’t hurt either)
• But even if: Usenet providers (hopefully) don’t keep logs of what you downloaded, so for all we know you just paid the provider to download actual news/Linux ISOs?
• But even if they do: You are not uploading anything -> you are probably less interesting to law enforcement and they might just ignore you (especially if you use some payment method that might require going through some extra steps to link it to you as a person)

This is the correct link: https://revanced.app/ or even Github directly: https://github.com/revanced

I think revanced . net should not be trusted
