A List of ALL the "Agreement" Checkboxes

Just like I did to gain access to Norton Community, I am constantly asked to click on the checkbox for agreeing to a sites guidelines et al.  And, I've been doing this … well, FOREVER since discovering the Interwebnet.
Some of these are for simple acknowledgement of the product's needs. Others might be more questionable.

Wouldn't it be nice to know which of the these applications and sites are STILL receiving access to my information?  I'm sure there are some that I no longer have a relationship with that may still have my "agreement" on file.  

How could I find out who these entities might be?
