A good amount of URLs on that list are under the LAT/WP umbrella. Newsday is one that I can remember as LAT owned.
I said it before, I'll go them one better and never go to their websites at all.
I know this is the hard way, but if I saw an important article at one of these places, I did a search and tried to find that article at it's original non banned source. It works sometimes as those people at the LAT/WP don't write everything.
Yeah, sometimes that works.
But ya gotta watch-out for the other way around as well.
As an example, just a week or two ago I excerpted an article from the Pittsburgh Tribune-Review (not normally required) because they had picked it up from the Washington Post (where it had originated).
