List of domains currently known to be blocked by the Internet Watch Foundation

(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 (which is their server) as a reply for a query for a blocked domain. On, 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!
