Thanks for the info, WassabiCracka. It's really up to Neighborhoodies.com to decide if they want to fight this, as they were the ones selling the shirts (I made no money off of them.) I will pass your post on to them.

They also sent both us and Neighborhoodies a DMCA take-down notice. We had 5 days to take it down or they would force our host to turn our sites off. Scott did not get one of these as of yet.

Just to be clear, Improv Everywhere and Neighborhoodies got a C&D over the Blue Polo shirts with yellow "Improv Everywhere" price tag logos, not the t-shirts. We're in fact still selling the t-shirts (bargain price of $5.99 + shipping.) I guess the thought of people buying the polos and wearing them into Best Buy stores scared them into doing something about it. At any rate, I don't have the money to fight their big bad lawyers as I'm just one dude with a website, and since I wasn't making money on the shirts I can't counter sue for loss of income.

The T-Shirts you can see are still on sale here:

And the original prank that started all of this is here:

PS: Yes, it's completely outrageous that Scott got a C&D for blogging about us. Unreal.
