Mr Santos, who labels himself a “former congressional ‘Icon’” on the platform, is selling personalised messages recorded by him for $200 (£159) each.
On Friday, he became the sixth lawmaker in history to be kicked out of the House.
It came after a damning House ethics report accused him of fraud and lies.
Among its many allegations, the panel accused him of spending campaign money on Botox treatments, credit card debt and OnlyFans - a platform where users pay for content, including pornography.
On Mr Santos’s Cameo profile he describes himself as “the Expelled member of Congress from New York City”.
Cameo is a service that allows fans to buy personal video messages from their favourite celebrities.
Dude I hate the GOP but this man is an icon.
He’s like the post modern artist that politics didn’t know it needed.
He’s truly a masterpiece.
I’d rather this guy’s antics in the news than just about any other political figure.
He could straight up be a hot dog vendor guy in NYC tomorrow, and I’d click that link.
He’s the entire Republican id distilled into a human shape.
Like, if he knows, he’s on the order of Andy Kaufman.
That’s what the deep state, Soros and gay frogs want you to believe.
He’s basically Dibbler from the Discworld books.
