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.
There are some cringe worthy ones from Guiliani.
I believe you, I’m just having a hard time wrapping my head around individuals who collect such things. A museum maybe, but were I a curator, I’d go for somebody of actual interest and cultural value.
I can even see how fascists would give cultural value to things owned by fascists. But this guy is just a con artist.
