While poker seems to like what tweeting from the field of play brings to the table, tennis people — specifically the Tennis Integrity Unit (wow) — do not want to see anything on twitter saying, “returning serve. whoa! that was close!” because of fears the communications will be misappropriated by gamblers.
The signs, written by the Tennis Integrity Unit, point out that Twitter messages could violate the sportâ€™s corruption rules. Tennis appears to be the first sport openly concerned about Twitterâ€™s possible effect on gambling.
The signs say tweeting is not allowed on court during matches. They also warn about using Twitter away from the court, saying sending â€œcertain sensitive informationâ€ could be considered passing along inside information.
