>>82436298Faggot, true bronies posted on ponychan and /b/, and on other sites. The 4chan "bronies" you speak of were nothing more than trolls. The ones who liked ponies for anything other than how it could be used as a trolling tool, or because they were fans of the fandom, hated bronies and hated being associated with them.
See, when MLP took off, trolls noticed something. They noticed the butthurt that /co/ exhibited in pony threads. /co/ of all places got their panties in a twist because of a little girl's cartoon, despite the whole board being dedicated to shit that is largely aimed at children, which was hilariously ironic and did not go unnoticed by the rest of 4chan. This made us a laughing stock (yet again), which made our hatred of ponies even worse. Thus the butthurt got worse, so trolls started spamming it everywhere even more than they were. The rest of 4chan's anons also got butthurt, which snowballed out of control for a few months. It had died down a lot by the time /mlp/ was created. /b/ was still irked by /b/rony threads but not as much. /co/ and MLPG had come to some sort of equilibrium and uneasy alliance since both groups fucking despised bronies and any pony posted outside of the MLPG was either by a newfag or a troll so MLPG was usually left alone. Sometimes not, depended on how mods felt at the time. /v/, being the festering shithole it is, had the biggest pony problem out of any board, though it really wasn't as bad as it was in 2010-mid 2011.
Naturally moot made /mlp/ anyway, which reinvigorated the trolls and made the problem serious again, for a few of weeks because MLP was back in the limelight. Moot was a faggot who loved to stoke the cancer fires, so there was a lot of speculation that he made /mlp/ just to create another MOOOOOOOOT moment to add to the annals of his cult of personality.
