If you must know, there is a troll online antibrony group called GNAA actively spoofing the email addresses of Hasbro lawyers and issuing false Cease and Desist notices. They got PurpleKecleon’s “Hot to Trot” doujin pulled, and tried to take down the flash with the special bonus image folio I made at TJA as well (not that it really matters since sales dry up after initial release and I leave leaks alone once they drop off). They have a long history and you can find out about them on Encyclopedia Dramatica, if that’s your thing. The notice sent to doujinpress is not clear if it was a spoof or legit so they are playing it safe.

So the answer is, if you put it somewhere where this kind of thing can be pulled, reported or simply try to cause problems, there are people that really have nothing better to do than to do just that, no matter how insignificant the effect.

I found out about it from a friendly anonymous who knows an ex-GNAA member that this was on the mailing list: http://i.imgur.com/dajvx.png I had told no one about the message I got about it from TJA earlier that day so I was pretty damn surprised to see this. There was no other way they could have known; there was no notice on the site or anything. According to their Twitter feed, they’re also taking credit for nuking many clop tumblrs.
I also talked with one of the Hoofbeat artists and he said that they took pseudonyms and do limited print runs at conventions to avoid problems later. Don’t forget, that guy that made the Lyra plush got hit by a C&D as well that was probably unverified.
Even Zone gets real takedown notices from Cartoon Network and Nintendo. You almost have to keep it small in order to fall within parody law and other works. I know that a lot of people won’t have the frame of reference to write about this or even know the details, so that’s why I spoke up.
So that’s something to consider. The more you know.
