Tripadvisor Certificate of Excellence

We were on vacation in Greece and Turkey a few weeks ago and I noticed many TripAdvisor Certificate of this or that, hanging in windows of random shops on remote islands (and big cities) and I got to thinking, are these for real? Is there a simple way to get a counterfiet certificate? It's just a piece of paper and I somehow doubt that TripAdvisor in Massachusetts USA is aware that "The Citadel" shop on Santanelli is sporting a fake certificate.
