mikfoz is a user and former moderator of Facepunch. He was well-known for being a very active moderator, and for being much older than the average Facepunch user, being in his late thirties according to Hezzy. He famously resigned as a mod and permabanned himself on December 19, 2008 with the ban reason "And then one day you wake up and realise you've just been pissing in a sea of piss..." The phrase "pissing in a sea of piss" became a meme on Facepunch.
mikfoz was silently unbanned at some point, and posted for the first time since the incident on July 22, 2009. He is active today, but rarely posts.
