I’d assume that is happening as well. This fandom has gotten awfully Balkanized, wouldn’t doubt it if that were true. There doesn’t seem to be many inside jobs anymore either.
I remember that Equestria Girls to begin with was leaked by a person who presumably worked at DHX or Top Draw and was dissatisfied with either their job or the fandom, since it got leaked on a hateblog first.
Oh, and there were several anons who impersonated people who worked at DHX and people widely believed them. Things like songs about shopping, all of the mane six going through the portal, and Flash Sentry saying things to Twilight like “You’re my princess” and the fight that the mane six had over Flash in order to get his attention. All fake.
Honestly, this makes me wonder who at DHX or Top Draw are constantly leaking this stuff. I always assumed that Top Draw employees leaked everything since they were involved in finishing work and thousands of miles away from prosecution, but after hearing that it was someone within DHX that leaked the Flash puppets I’m not so sure anymore.
