Website sales and revealing the domain

If someone is selling a website, it should be necessary to reveal the website with the real domain name or with a url shortner.
Lots of (new) members are overwhelmed by Adsense numbers and traffic stats, and don't recognize a scam when they see one.

If a website is to be seen by all the members, a scam is much more easier to notice.

 

There are a lot of reasons people wouldn't want to show the url in public. It's up to the seller to decide.
