>>318521/vt/ does have a similar energy, but /mlp/ has gone through alot of fuckery from 4chan and the show itself. Between being forced into becoming a blue board despite being NSFW for a considerable period of time, the brief /pol/ and /mlp/ fusion being akin to a colonization/repopulation (ironically something /pol/ hates) which in turn forcibly altered the userbase, the show crashing and burning hard in the last two seasons, and a minority that prefers a spinoff's cartoon humans to the ponies constantly spamming the board, /mlp/ is fucked beyond belief.
Not to mention that the moderation team for that board seems ambivalent at best and actively hostile at worst to the userbase. The only thing that keeps /mlp/ going right now is hate and spite (ironically) with a side of horniness as they rush to create their own spaces in the internet for themselves as everything else is being corroded or ripped away infront of them.
Also, obligatory fuck mods and fuck jannies.
