It's hard to identify any disruptors, which might have been the case, after the elections everything will be fine. Lots of trolls going around right now.

We will be taking a number of precautions to keep out disruptors on Election Night, but invariably some will slip through. If you see a disruptor, please hit the "Alert" link on their post so the moderators can deal with them quickly. Do not assume that someone else has hit alert. In most cases, nobody has.
Some folks have been bragging on other websites that they are going to "unmask" on election night after racking up thousands of posts on DU pretending to be liberal. I am hoping that this happens. I get a great deal of pleasure from the idea that some moronic freeper has wasted months of his life pretending to be a liberal on DU. I get even greater pleasure from the thought that after all that work there is a good chance that their big "unmasking announcement" will get deleted after about 30 seconds, and their account banned forever.
