(and many, many more; the list is secret, so we don't know…)
Only domain names are listed! Some ISPs block by URL using a transparent HTTP proxy, so these domains won't be shown as blocked from their networks.
Czech Telefonica O2 filters using a fake DNS - they return A 18.104.22.168 (which is their server) as a reply for a query for a blocked domain. On http://22.214.171.124/, there is a webserver running showing "(HTTP 403) Access denied" in a HTTP/200 response.
If you know any other blocked domains, send them to me (jenda at hrach dot eu). PGP key can be obtained here (HTTPS). Thanks!
