So I forget what site i went to, but I noticed that my pathway to their site wasn't encrypted. So I started poking around, and found a list of sites and servers that have "permission" to ping me and such. So, me being a numbnut, I proceeded to disallow nearly half the sites until I got bored of doing that. Now I'm having small problems getting to sites, or seeing images (lie icons on here). How do I undo the craziness I caused?
