CONTRA COSTA TIMES -- Nov 28 -- Robert Wells advertised himself on an online dating service as a semiretired physician who enjoys wine tasting, "The Sopranos" and reading science fiction. But a woman surfing the Web site recognized the Walnut Creek man from another dating site she'd used a year earlier. She told the current service, Dallas-based True.com, that Wells was lying. Not only had the medical board revoked his license, according to a lawsuit, but he also was a convicted sex offender. The company sued Wells earlier this month in U.S. District Court in Texas, alleging Wells committed fraud by misrepresenting himself. "I make a promise to my members," said Herb Vest, TRUE's CEO. "If you are clever enough to get around our site securities, I'm going to prosecute." TRUE is suing Wells for at least $200,000. "If anyone who's married or has a criminal conviction thinks they can get on our site, go ahead and try me," Vest said.
