Sharkscope fetches the result from
real money games for several
poker sites.
As a free user you can do 5 searches per day.
If I search for you, I can see some basic statistics: You play around 3 games per day on average are are ITM about 13% of the time.
And you mostly play micro levels since you're average buy-in is 0.43€.
If you don't want to be looked up, you can opt-out of the site. So your results will be blocked.
If you want to use sharkscope for yourself as a tracker of results, you can opt-in on the other hand and see much more statistics of yourself but also everyone will see those.
You can compare the two levels of info, if you search for yourself and for me, for example as I have opted-in to see more statistics of my results to understand where I might need to improve my game.
