What do the pedophile symbols look like?

According to the FBI and the NCMEC here are some of the symbols used by adults who are attracted to children to identify each other:

Boy lover - Smaller triangle inside a larger triangle.

Girl lover - Smaller heart inside a larger heart.

Child lover - Triangle containing a butterfly made of hearts.

Pedobear - While this is actually a symbol to warn that there are possible pedophiles in an area, there have been reported incidents where suspected or convicted pedophiles have used this symbol themselves or wore this as a costume.
