I have a Belkin router with Connectsafe turned on and set to the highest level of blocking. I am curious what websites are blocked or not so I did a bit of testing. It lists gambling as a subject blocked but three out of four "top ten online casinos" are not blocked (for example bovada.lv). I tried two famous adult websites and neither one is blocked. I looked for a site where ratings can be checked but can't find one. I found safeweb.norton.com but that doesn't seem to return results matching what ConnectSafe is blocking.
How can I determine which sites are and are not blocked, and why are so many online casinos and adult sites not blocked?
