Can confirm. I remember my seeing a first “hey, did you guys by any chance happen to see the new episode” post on /b/ back in 2010, quickly followed by it exploding on 4chan and people setting up the first pony tf2 servers, moot creating /pony/ as a containment board, and everyone saying “don’t post on /pony/ or you’ll get IP banned in two weeks” - because a decade prior, moot had created the /furry/ containment board when furries got big, let it sit for two weeks, then IP banned everyone who had posted to it and deleted it.

Of course, he didn’t replicate the action with /pony/, which is still around. And early brony culture was fascinating, because on a site where shock humor ruled and the experience was like digging through a sewer to find gems, suddenly a subculture emerged that was heavily anti-irony, kind, and genuine. Absolutely bizarre to watch.

Worth noting, as others have, that this was pre-gamergate, which was the social movement that took 4chan and turned it from a place that let Nazis post (usually “iRoNiCaLly” under the premise of being part of the ocean of piss that was the shock humor on /b/) and rolled it into a full Nazi bar.
