Whats wrong with Bidvertiser?

Tweet

I started a blog long time ago and set a Bidvertiser code there, the same day I set a view counter. Now my view counter marks 209000 views on the blog. But I log in at bidvertiser and the clicks are still 0. The status of the add is Running, and I can actually see the add on my website. How is it possible that no one clicked on my add, ever? I actually need a advertisement website that pays to paypal, but not sure if i should use bidvertiser. Share your experiences with it
