I should have added that I periodically look at that page. The preponderance of lefty sites in the related sites section is new. Either those who browse those sites to see what the adversaries are up to have stepped up their activity, or it is what I suggested that I think it is- trolls.
Plus, it is not like this list is of the sites most Freepers would go to in order to check up on the left. Some of these are pretty obscure.
