Here are two ads from People for the Ethical Treatment of Animals and two from a group of content creators in Second Life. See a resemblance?
The content creators are lamenting an all-to-real problem in-world, the theft of their intellectual properties. Lamentably, however, they are ripping off PETA's intellectual property by copying the look-and-feel of the PETA ads. Even if they have permission from PETA-- which I somehow doubt-- the creators' point could have been made in a more original way.
My thanks to Sweetie, who originally pointed out the connection between the two series of advertisements.
