I signed with brainfox 3 days ago, and put $50 on my account. So I receive additional credit of $25.I bid .02 cents on ketwords. Within 3 days I receive 100's of click(my balance is $37.00 today). Guess what I look into my log and see none of those click have 2 click, they come to url I provided and left. Now compare with with adwords or bizrate, 90% have 5-10 clicks after they visit the site. So basically they are ripping people off, stay away from them Also guess what they wont give me that money I have left there.
