You are allowed to sell your soul on eBay.

False. You can’t sell your soul on eBay because its policies prohibit intangible items and anything related to human body parts. Listings must be deliverable, physical goods or clearly defined services. “Soul” sales have been taken down in the past as jokes or policy violations, since there’s nothing to ship or verify. Contract law backs this up: an agreement to sell a soul is unenforceable because the subject is intangible, impossible to transfer, and contrary to public policy. Memory tip: If you can’t package it and ship it, you can’t list it on eBay.
