As for Sky, the block is done at the DNS level. Digging the domain from their DNS servers returns their "blocked page" ip address, Change which DNS servers you use and the site isn't blocked any more. Guessing they can't do DPI on the IP address for the site as its hosted behind Cloudflare. Problem is I recommend Sky customers change their DNS settings anyway (either on their device or on the router, but the router method requires saving a config backup, editing that backup and reapplying the backup because Sky don't expose DNS settings via their routers UI - or at least they didn't, dunno if they have changed that in recent routers/firmwares) because a lot of "connection drop outs" on Sky are related to their DNS servers failing, use another DNS provider and those issues are gone (but you also lose their "broadband shield" filtering) EDIT: Also their backup domain isn't block by Sky (but Sky have waves where they will also block backup domains so that might change esp as this is a new block, though one site (that might be on their block list because of a court order) back up domains haven't been added to the list for something like over a year now, so not sure if Sky gave up on the cat and mouse game. EDIT 2: Just to add, it seems that this site is only blocked when the customer has the ISP filtering enabled, if you have turned them off the site isn't blocked. So while I'm against blocking, at least this block can be turned off if the account holder desires unlike the court ordered blocking.
