The Federal Bureau of Investigation's official documentation (see screenshot below for page) regarding the symbols reads as follows:
(U) Symbols and Logos Used by Pedophiles to Identify Sexual Preferences (U//FOUO) This intelligence bulletin addresses Crimes Against Children Standing Intelligence Requirements Set contained in Q-FBI-2200-005-06, HRWC CAC-VI.A.5. (U//LES) Pedophiles, to include those who sexually abuse children as well as those who produce, distribute, and trade child pornography, are using various types of identification logos or symbols to recognize one another and distinguish their sexual preferences.
To specifically indicate the pedophile's gender preference, members of pedophilic organizations encourage the use of descriptions such as "boylove", "girllove", and "childlove."
These symbols have been etched into rings and formed into pendants, and have also been found imprinted on coins. The BoyLover logo (BLogo) is a small blue spiral-shaped triangle surrounded by a larger triangle, whereby the small triangle represents a small boy and the larger triangle represents an adult man.
A variation of the BLogo is the Little Boy Lover logo (LBLogo), which also embodies a small spiral-shaped triangle within a larger triangle; however, the corners of the LBLogo are rounded to resemble a scribbling by a young child.
Images of the BLogo and LBLogo symbols are depicted below.
FBI investigations in several cities have uncovered several symbols used by pedophiles to proclaim their attraction to children.
After a seizure of a subject's computer in connection with an Innocent Images case in the Jacksonville Division, a Computer Analysis Response Team forensic examiner came across an unfamiliar symbol that was integrated into a Web site banner named "ATBOYS.COM, where the "A" in "ATBOYS" was actually the BoyLove symbol and written as follows: TBOYS.com.
It was further determined that "ATBOYS" is an acronym for Attracted To Boys.
These pedophilia symbols also appear on Web sites such as one of the banners advertised
