Con: a ruse used to gain another's confidence.

Texas is suing a Christian "influencer" for falsely claiming she could cure eating disorders, Insider reports.

The state accuses Brittany Dawn of misleading customers about her expertise and of falsely promising custom nutrition plans she never delivered.

A self-proclaimed "Jesus seeker" with a half million Instagram followers, Dawn also promised customers regular phone check-ins that never occurred and charged them "shipping fees" for emails.

Allegations against Dawn first surfaced in 2019, when followers began to call her a "scammer" on her Facebook page. Their complaints led to an investigatory report on ABC's Good Morning America.

When the heat grew too much to bear, Dawn shuttered her nutrition business and turned to monetizing Jesus, producing hotel shows for vendors of Christian tchotchkes.

    Jesus clears the "den of thieves"

Brittany Dawn is only one of thousands of scammers we innocents encounter on line every day.

They've made the web a den of thieves.

But who was America's first big scammer?

The credit goes to William Thompson, known to history as the original "confidence man."

Operating in New York City in the 1840s, Thompson would dress up as a gentleman, walk up to a wealthy mark on the street, and begin a conversation, as if an old acquaintance. After a minute, Thompson would borrow the mark's watch, then disappear from his life forever.

Thompson's haul each time was considerable. A gentleman's watch in the 1840s cost $4,200 in today's money.

Thompson capitalized on the instinct of the genteel to avoid a faux pas at any cost; in this case, the cost of a fancy watch. His consummate skill at appearing trustworthy earned Thompson the newspaper nickname "Confidence Man," a moniker that quickly became synonymous for scammer; and, in its shortened form con, synonymous for scam.

Herman Melville immortalized William Thompson's nickname in 1857, by using it for the title of a novel. 

The Confidence Man features a cast of characters who are card sharps, stock swindlers and snake-oil salesmen, cheats who Melville thought symbolized all that was wrong with America.

NOTE: The word scam, by the way, entered American usage in the 1960s. Meaning a "trick," scam is a carnival barker's term derived from the 18th-century British word for a "highway robber," scamp.

POSTSCRIPT, FEBRUARY 10. 2022: Axios today announced that Maggie Haberman's Confidence Man, the "book Trump fears most," will be published in October.
