Gsa index check and scrapebox = different results

Hello guys

i'm having truble checking index urls from gsa, it gave me very different result from scrapebox

does any one have any idea why ?

i'm using the same proxies ( 20 ) 

We had this a few month back, when I manually did checks scrapebox was much more accurate and you can use a much shorter delay for your proxies without getting soft banned.

thanks
