Exception

Exception is the nickname of a participant in Bitcoin-OTC, a do-it-yourself over-the-counter trading network where users rate each other via a web-of-trust system. The platform and its WoT model emphasize pseudonymity, so a specific real-world identity for the user “Exception” is not publicly verifiable within the Bitcoin-OTC ecosystem. In short, Exception appears as a user/pseudonym within the OTC trust network rather than as a publicly identifiable individual. (en.bitcoin.it)
