ROSYNA A few notes about your review. SCR isn't causing Safari to crash, it's appearing because Safari crashed. That's why SCR was created, to report crashes to the developer that isn't Apple.
I'm not sure why you claim it is spyware or sending hidden data. SCR tells you explicitly the name of the developer the report is being sent to and lets you see all data that is being sent, allowing you to choose not to send it. This is because it's actually what Apple's crash reporter is doing.
