I posted something similar about how pedophiles use Bittorrent to download child porn. They use similar codewords to know what they're downloading.

Excerpt:

• AoA: Short for “age of attraction” meaning the age groups of children they are attracted to
• MAA: Minor attracted adult (used in reverse of the word “pedophile”, though it is the same and places the child as responsible for the abuse)
• AoC: Age of (legal) consent
• CL: ChildLover/pedophile
• GL: Girl Lover/Attracted to girls
• BL: BoyLover/Attracted to boys
• YF: Young Friend, used when speaking about a victim
• CP: Child Porn (Which could mean anything from photos of naked or half-naked children to photos of actual child rape/torture)
• LG: Little Girl
• LB: Little Boy
• GM: Girl Moment – which is time spent with a young girl (that can either be a passing second consisting of nothing more than a glance or a smile, or a lengthy visit with a girl);
• BM: Boy Moment – same as Girl Moment

Then there are the chats, or message boards:

• CG: known as Common Ground, a place for pedophiles of both preferences. Common ground, while being the one that touts of being for “all” pedophiles is less used than either of the other forums:
• GC: GirlChat- for those that favor victimizing girls
• BC: BoyChat- for those that favor victimizing boys

and Pedophile Organizations:

• NAMBLA: North American Man/Boy Love Association
• IBLD: International Boy Love Day – this is an actual Pedophile Holiday celebrated by them on June 23 of each year.
• Newgon: Pedophile version of Wikipedia
• CLOMA: Child Love Online Media Activism

The fuck is Newgon? Someone safely look at that thing.
