This has been known for a long time. It's been said several times not to leave the 4 - 5 digit code in pics or videos that you upload. Also, you should be careful about other sites where you post pics, as they *could* be setup by RLC specifically to catch people.
Why can't these people keep their kids off cam? I don't care if they are fully clothed, they don't belong there I don't want to see kids, they can't consent to being on cam. Why is that so hard? WW needs better mods, its bullshit. I would never put a my children on a publicly available webcam.
