Ex_Brit: "It is there for 30 days only and is constantly updated and only goes back to SiteAdvisor's servers if you have opted in to the product improvement program, something that would have been asked when you first installed it."
I installed SA more than 2 years ago, and back then I had not expected anything like this.
It kinda reminds me of Google that originally set their cookies to expire 30 years later. Sure they thought it was a good idea to track people almost infinitely, and they didn't intend to abuse it, and so on... but users didn't like it, and in the end Goog changed their cook.
But of course, one could also disable SA temporarily, to avoid 'making history'.
Right! Or am I wrong..?
