@joepie91 amd without ISPs filtering shit and #denylisting stuff, the Internet would've beenBripped apart by DDoS attacks and shit decades ago.
ISPs fiddle with traffic all the time cuz shit's breaking all the time.
And being able to block malicious traffic by blackholing it at peering routers or IX level, stuff is kept working for longer than CloudFlare exists!

Everyone complaining about HEnet doesn't know how ISPs work!

@LunaDragofelis @freakazoid @schratze
I konw why one would want that, but it would kinda brick it.

There's a reason why decentralized systems like #eMail, #XMPP & :activitypub: work on #DenyListing instead of #AllowListing, as this would inherently result in #centralization to an oligopol, something we see #iEmail like #Gmail, #YahooMail and #Microsoft #Outlook attempt.

Also do you really expect instance admins to vet every single self-hosted instance?
Cuz that won't work for a lot of people.

@freakazoid @elias then you misunderstood how a federated system is intended to work.

Likewise with eMail, #DenyListing is the prime way to (silently) block adversaries (i.e. Spammers & Malware distributors)...

@freakazoid I don't think this will benefit the users but only act as an easy to jump-over fence for #hategrooming orgs like #KiwiFarms...

Having them burn through costly domains is a more effective deterrent, and #DenyListing / #Blocklisting is a proven strategy...
