I know it's a thing here to insist that every DUer is lying their ass off all the time. As far as the regulars go, there are some for which that's true. Aside from them, and some GoFundMe leeches and attention whores, though, most of them are saying things as they understand them, based on the facts (Or, more often, fake facts and BS propaganda) as they picked them up. I don't personally believe most of them are anywhere near as bad as their megaposters.
ETA - of course, at least 10% of the high posters are moles, and probably a quarter of the membership has been banned over time for either having a few too many lucid moments, stepping on boobytrap like pissing off the fembots and the gay mafia, or checking the wrong block in a poll.
