Is money earned from e-commerce permissible or impermissible, given that the website's terms and conditions, which stipulate no buying and selling, were accepted but not adhered to?

If the goods are permissible, then the money earned from their sale is permissible. However, a person is held accountable for violating the website's terms, because the Prophet, peace and blessings be upon him, said: “Muslims are bound by their conditions.”
