Confused at the ads

Today I saw some new ads showing on my site: http://www.nameslot.com

I didn't clicked the ads but opened a new window and typed in the URL of that site. Just to see what will the visitors see upon landing on that pages.

And when I went to that page it was saying cannot find server.

When I checked the whois it says Domain is registered but no website.

Any ideas why this kind of ads. Thanks.

Update: Now domain shows unregistered.

 

site may be under dns propagation period or something. you can use a proxy to verify.

 

Yes I checked it that way too. But there was no site at all.

 

have you used the site archive to see if it was old site? or use google to search for the site name?

 

ive opened the site on a new window. yes the site parkandpaid.com maybe down or dns has not yet fully propagated.

 

Searched google for it. No Results.

Checked archive.org. No Results.

And BTW. Then domain itself is still available. It is not even registered.

 

Never seen something like this before. hmmmm.
