Facebook[1], Google, etc all use (or used to use) MarkMonitor that offers domain squatting monitoring as a service[2] that utilizes the Uniform Domain Name Dispute Resolution Policy to remove offending domains violating their trademark. These services are quite expensive from my understanding.

[1] It appears Facebook now utilizes their own internal registry.
