Have a cheating mate? Catch him here!

Ok ladies! I want to know if any of you have heard of either of these two sites: dontdatehimgirl.com and playerblock.com? These two sites allow you to search for men who have mistreated or dissed other women. You can put in a persons phone number or capture a picture of their face from your computer and upload the information and then dog them out to the world! I'm assuming the mission here is to keep the "bad" guys from doing any other females wrong! Hmmmm...do you all see a potential problem with this? I do! I think it's wrong to be honest! Now on the flip side, I would like to know how a man has treated his ex, if that information is available to me! How do you all feel about it?
