Who this old Minecraft let's play was?

I remember that I used to watch a Minecraft Let's Play series, but I have no idea which Youtuber was. All I know is that it was a group of people who have built a pretty big base in this Let's Play. Somehow there was sometimes an event in which for a series other Youtuber were there. Does anyone know who that might have been?

Maybe freedom from palutes and GLP or craft attack from up to 30 people
