What is the problem?

I am really wondering that what is the problem with bidvertiser these days!I mean this site is definitely a genuine site and I know a lot of people who has been paid by this site.This is not as good as Google AdSense but also not a very bad one.The minimum payout in this site is only 10$ which is a great thing for sure.But very recently in spite of showing advertisements it is displaying a message like "Your Ads Here For Free".What happened to them?Are they running out of advertisements these days.I have also heard that even if a visitor clicks those messages it is not paying any money to the site administrator.

Bidvertiser has been a great pay per click campaign so far and I wish them all the luck to come back soon.
