so you wouldn’t answer if I asked what video a gif came from? (just trying to understand “source”)

Yes, because:

A) I can’t possibly answer every single question about the hundreds of videos I’ve gif’d.

B) I can’t freaking REMEMBER the hundreds of videos that I’ve gif’d… (They’re not from the same site or the same production company. They’re from dozens of places – just to start!)

C) My askbox is already flooded with so many questions for me to answer that it feels like I’m some tumblr x-rated version of “Dear Abby”. I can’t even keep up with that!
