Association of Sites Advocating Child Protection (ASACP)
This isn't about the dating sites, so don't bring the drama here please? Just throw a few dollars or more if you have it to spare to ASACP anyway. It's still a great cause, and they can really use the help.

If you're unable contribute, but come across what you believe to be a site distributing child porn. Report it here:

Every small amount of effort helps.
