It seems that DeviantArt administartion started a war with captions authors. Lot of them are already deleted and many will be in the upcoming days, I afraid. They're deleting mostly captions with photos of real people and celebrites, saying that that authors need a 'permission form' from the model in question.
It's sad, because TG captions are one of the most popular kind of art in TG fandom. We can hope that someone will change it, because all the parody and manipulation stuff is still accepted here. So why not TG captions?
