I think its OK but I if I was wearing a porn sig I think people would take what I have to say even less seriously than they already do... I can imagine it going something along the lines of:

Me: Craig Wright is a fraud. There's no way he's Satoshi, man. How can you guys believe that stuff? Plus that Calvin Ayre guy is pretty creepy.

Them: Yeah well at least we're not advertising porn in our signature space.

Probably just gonna stick with Bit Blender.
