I see providers web sites with something like "let's meet on easysex".  From what I can find on-line, the site is a total scam and perpetrates fraud by asking for a credit card for "age verification".  Fraudulent charges from sites you have never heard of start showing up.  Search "easysex.com scam" there is lots of info.

I know other providers have popups for sites like Ashley Madison, While it seems like there are virtually no real female members, at least the only charges are ones you agree to.

Then there are sites who, just like google, have ads on the sides or bottom of page.  No pop-ups and I assume the sites are legit (but have never clicked on one).

Thoughts on the ethics of intentional links to sites like easysex
