I so should get wptavern.ca .org and .net right now as I type this :)

I AM JOKING.

I am sure Matt can't afford to go the Google way (Are you aware that Google owns every variation of Google and all the CCTLD and regular TLD?).

If a website is violating your TM

Step one: send an e-mail from your @domain.com address (since now a days unlimited addresses are given, create a new one).
Step two: If things don't happen then you e-mail the webhost and if it's different the domain registrar. If the website has google adsense or other advertising networks/affiliates, then CC those networks and the owner
Step three: e-mail owner a third time

That should work most of the time.
