Sites doing mass IP/ASN/etc blocking, and lying to the user about it:

Site	Lie
cpu-world.com	Connections silently dropped
crt.sh	Connections silently dropped
dominos.com	Everything works except the final API call to submit an order silently fails
etsy.com	When registering an account: “Sorry! There was a problem on our end. Please try registering again or email support@etsy.com for assistance.” Support@ address auto-replies with “This is not a monitored inbox.”
imgur.com	Returns json claiming imgur is over capacity and a 403 status. HTTP status is actually 429. ~~Direct image links (i.imgur.com) work~~ Nothing works anymore
github.com	SSH connections are silently dropped after key exchange. Also sporadically blocked from search for “abuse”
gofundme.com	Claims 502 bad gateway
he.net tunnelbroker	Connections to common IRC ports are blocked
padmapper.com	Returns fictitious HTTP 433 for all requests
segaretro.org	All edits blocked as spam
twitch.tv	Firefox+Linux users are blocked from doing anything related to accounts
*.weebly.com	Connections silently dropped

“Honorable” mentions:

Site	Details
10minutemail.com	IPs/ASNs blocked via cloudflare. Hilarious that a site mostly used for spam registrations would block anyone
auth.meta.com	Clientside JS broken in Firefox while setting up 2FA, error message is a lie
buyee.jp	403, no message
discord.com	New account creations are instantly phone-locked
facebook.com	Forces login, even when browsing public profiles (such as companies)
instagram.com	Forces login. Account creation is also effectively impossible
kabum.com.br	At least returns HTTP 403, but the text is not helpful
rateyourmusic.com	Honest. Has a detailed splash page explaining the block
vrchat.com (all domains/services)	Used to do mass ASN blocking. Web requests would get a cloudflare block page, but API calls from the client would fail in non-obvious ways. Seems to be reverted since 2FA was forced on everyone
