at least when you share you experiences with evidence that will help us to make a sound judgement
But in your own case, you just came here and make some accusation with backing it up with evidences. don't you think it will be more nice if you drop your evidences....
People need to be real careful when they search anything on line. A lot of "idiots" who do these works need info such as your Social Security number, bank info, etc. I am smart enough to know if I need to give such info out, I check everything out real close. Kids or teens are another example. A lot of parents don't usually stay by their kids when they are online. We all hear many times that children are victimized. So if you notice anything suspicious, always check it out. Ads or scams are not worth it.
