You might know that I'm generally against things like sexualizing ponies and the concept of Princess Molestia. That's why it might confuse you to know that I really like JJ's ask account on Tumblr.
It's hard to say why, though Willow, acting as my proxy here, covered most of it. In generally, it's not mean-spirited or crude and the artwork IS phenomenal. Plus it's just naughty enough to be entertaining without being crass. Not to mention it just makes me laugh.
