Artist Disillusionment: Hannah Rutherford has admitted to being fed up of Tumblr, in part due to fans that deem her content problematic without watching it and in part due to some incredibly warped fanfiction which she understandably wasn't amused by.
Big Name Fan: A freelance editor and Yognaut called Ryan Horton, known as YorkieRaz, has made a couple of montage videos that the Yogscast in general went on to use. He was even commissioned to make one for Strippin after he was piled up with work. When he donated in the 2014 livestreams, he got a Shout-Out from Lewis, Simon and Strippin for all his hard work.
Creator Backlash: The Yogscast, in particular Lewis, do not seem terribly fond of the time that Gamechap and Bertie were members, having publicly mocked them many times in livestreams, as well as on social media.
Defictionalization: It was a running joke for a while that the Yogscast were based in an office called Yog Towers. They've since gotten an actual office, which they've taken to calling Yog Towers.
Duncan picked up the nickname Druncan (also spelled Drunkan) during the 2012 livestream.
Nearly everyone has a 'gin rage' related nickname actually. Sparkles* admitted to being called Drinkles (owing to him coming in to part of the livestream extremely drunk) and during the 27th Dec livestream, they thought up Brewis Ginly for Lewis. Strippin is Sippin, Simon is Honeybrew, Sjin is Tsjipsy, Zoey has her fake last name changed to Drunkasheck, Martyn becomes Martyni (even though that isn't what he drinks) and so on.
Fandom Nickname: Fans of the Yogs are called "Yognau(gh)ts", although the spelling of the term varies. It depends on whether you prefer Simon or Lewis.
Old Shame: Lewis has publicly voiced his disapproval of the Yogscast's prior involvement with Game Chap, openly bashing them in the 2014 livestreams.
Despite being a general gaming channel, the Yogscast (or at least Lewis and Simon) are almost universally known as theMinecraft channel note besides the official one: Notch, the creator of Minecraft, frequently tweets about the Yogscast's Minecraft videos, and at GamesCon 2011 they officially represented Minecraft. Simon even got to wear Notch's hat! They've also gotten to play competitive Team Fortress 2 matches with Notch for charity.
Tinman, one of the old admins of the site, was eventually fired for rerouting ad revenue on their website.
Peva was fired after an internal falling out.
Game Chap and his friend Bertie were eventually recruited into the Yogscast, but were removed after a very rude response to some relatively mild criticism on the subreddit. Unlike the first two, they've been able to keep some sort of web presence since their removal.
Schedule Slip: In regards to Simon and Lewis' Magicka co-op with TotalBiscuit; the three had increasingly busy schedules starting after Part 8, and Part 14, a 40+ minute episode, had audio issues that TotalBiscuit still hadn't edited out yet when it was finally released two months after recording.
The comments on Rythian's channel, as well as the BlueXephos channel, were turned off in mid-2013 due to a host of people trying to scam Yognauts out of money, plus unnecessary spam. They were eventually turned back on.
