Er. Extremely bad fandom etiquette, and I think it's quite rude to the actors as well. (Note, I'm not opposed to RPS. I *write* RPS. And yes, it's on my website, and a few minutes with Google will turn it up, so it's within the realm of possibility that the actors involved have seen it. But I'm not going to hand it to them, because I want them to have the choice of ignoring / avoiding it.)

I really wouldn't recommend it, and honestly don't see what purpose it would serve.

Just my 0.02.
