Here are wantdataeast's quotes that triggered us to have even more, quite legal, fun!
Pinside moderators and pinside user using my Avatar as their own.
I am copyright owner of that alien image. In 1997 I commission that image created. Outside of his use of the image, I am the sole owner of its use.

Pinside moderators, I would politely request that you enforce this request.
My announcement of my images illegal use was your C and D, as it was to everyone on this forum's. Step 2 is being sued.
I admire your strength of will... you're really really brave a tribute to forums everywhere. Send me your name and address via PM and I will get the legal ball rolling.
