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.
This might be the most legitimate work Santos has done in his life!
Assuming he’ll actually fulfill the video requests he’s paid for? Bold prediction
He’s not even claiming to be a former president (yet)!
