As others have mentioned using a proxy would work..

Other ways would be using iptables to block access to those
domain's name servers so the names do not resolve at all(they could
still access via IP..)

Also hosting the domains on your internal name server and pointing
them to some internal address so that they can't be resolved as
well could work.

Often times client side antivirus/spyware programs can be configured
to block things on the client side as well.
