The WSOP* made a decision to make it as hard as possible for people to talk about them. Their new trademark guidelines forbid any web-master or publication to directly refer to them. Instead, if you want to talk about them, you need to indirectly refer to them with phrases like, “The $10,000 World Championship of No Limit Texas Holde’em, or The World’s Most Prestigious Poker Tournament.”
Additionally, you’re not aloud to post any of their logos, stylize their tournament name, or post either whole or part of a picture of one of the bracelets. And if you do refer to them in an acceptable manner, you have to post a disclaimer explaining that you’re not affiliated with them.
What are they thinking?…
YOU MAY NOT:
Use either the WSOP’s* poker chip logo or stacked logo, or any image of a WSOP bracelet in any of your advertising or in any communications to your players.
