I wonder if something like Slashdot's metamoderation system could be used to tamp down such abuse.
One problem with metamoderation is that once a particular forum becomes an echo chamber, even metamoderation will unconsciously but repeatably ignore "valid" information from the other side and amplify misinformation from their own side. But if the site owners specifically searched for good-faith users from multiple viewpoints to serve as the jury pool for metamoderation, this could be workable.
