If you're too stupid to figure that out then you're taking a huge risk to pursue jailbait booty from a fake person with a fake picture and profile of someone who looks like they're 18, but happens to be law enforcement undercover or a troll. Then you may be the next pedoshark to end up on the shark fin soup menu.
Old fart: Do you like popsicles? I fetch you one, you look purrdy, are you 18 yrs old yet?
Underaged Girl Decoy: I swear I'm 18, but don't call me jailbait, because I'm really a 16 yr old decoy and an undercover cop exposing pedosharks like you!
Random Troll: Hahahahaha you loser, get your pervert ass in jail!
Old fart: Fuck, I got hooked line and sinked! Shit...my fins!
