How do I block a car dealers listings?

https://www.trademe.co.nz/a/motors/dealer/cooke-howlison-toyota

has more irrelevant keywords in their ads then anyone else on Trade Me. The Trade Me help sections are completely useless and obviously built by morons.

Sick of seeing poxy Rav4s and other crap when searching for specific cars. Trade Me supposedly has a policy against it, but navigating the help section and even they contact section is a waste of everyones time.
