I see a load of porn sites. Just how does this Make The Internet Not Suck? (damn it's even more annoying to write incorrect casing than read it.) I thought this was going to block the fifty "Share this! Email this!" buttons on websites or something... If you don't visit porn websites, you won't visit these domains anyway; what's the point in blocking them in a huge hosts file?
With the exception of "The" the titling is just a proper use of titling case. Do you find it annoying to read newspapers? I imagine it is the awkward phrasing that you (and I) find annoying.
