What’s Manebooru’s purpose?

@Background Pony #37B7

Ponerpics seems to be a Derpibooru alternative with less rules. Ponybooru and Twibooru seem to be archives. What about Manebooru? It seems to be a Derpibooru alternative, but it doesn’t specify what makes it different. So what is its purpose?

At the time of writing, Manebooru is the only altbooru that has a rule against fascist and hateful imagery and actually acts on it.

I'm fairly certain this was pointed out in the original Derpi thread, but Ponybooru is the "Derpi-lite" site, DNPs and all, while Twibooru and Ponerpics eschew takedowns of rule-abiding content. Twi's got some novel features like text posts and MP4 support, whereas Poner hasn't had much in the way of updates since its inception, but it still chugs along so long as there's someone to poke the server when it derps out.
