The boy lover symbol was registered in the 1990s. That doesn't mean its use wasn't widely used before then. It would be good to know how old the badge designs are in light of this. As a former graphic designer the points of the badge lend themselves very well to this design. But, then again, if you google "copse busted for child porn" you will get about 8 billion hits.
