Strange but true

Tweet

A friend of mine observed this strange behavior of IE (not sure about the version). When you visit this MLM pages and you click on ads, open two tabs of the same ad and if you manage to click both withing the gap of 2 seconds it show your credit for both. I am not sure whether you really get the credit, but at least it shows that you have got the credit. It surprisingly does not happen every time. Any one can explain what is the reason for this and whether you really get the credit twice ?
