omegle pretty much
Oh right, forgot about that.
Whenever someone posts pics like that I go "NO" over and over, end it with "GOD NO" and "NOOOOOOOOOOOOOOOO" and then disconnect.
Two other good strategies: Whenever someone says "m or f" and number, say "f 16" or something like that and post a picture of a fighter plane thing lol
Also whenever someone says "kik me" I say "I will kick you in the face."
