This is a non-issue. As BI stated, I am sure that they restrict what is discusses/promoted on the show. Being on the show is about promoting Survivor, not speed limits, sports teams, etc. Any plugs for the Red Sox though is always appreciated around here.
On a lighter note, we made up pink thongs last summer with my company logo on them as a joke/gag gift for some customers and family. I'd be happy to send you one. Not dot.com on mine, just Globaltek....
