I'm a pretty big Tobuscus/TobyTurner/TobyGames fan and to declare his channels as responsible for the apparent uprising in childish behavior is stupid, I don't watch Sky's content but I also feel that it is not his fault for what his fans do. They didn't ruin minecraft, the more fanatic side of their fanbases are just louder than your average minecrafter so they stick out more. If you don't like their understandably annoying spam, use the /ignore command.
Also, of all the servers I play on, many of which have 5000 - 6000 members online each day before their peak I haven't heard 'budder'' or anything similar being said for a good few months, so I'd evaluate the quality of the servers you play on and how well the staff carry out their jobs in cutting spam.
