why didn't they take down banned from equestria?

"Banned from Equestria," a fan-made project within the My Little Pony community, likely remains up due to a combination of factors such as the creators' commitment to fan expression, a lack of enforcement from copyright holders, and the work's popularity among fans. Additionally, fan creations often occupy a gray area in copyright law, where companies may choose to overlook them to maintain goodwill within their fanbase. Ultimately, it reflects a balance between fan creativity and the original creators' interests.
