They are especially active on Facebook. None of them will have an actual picture of themselves posted. Just a fake or a picture of a cartoon or something, and a whole slew of posts on their pages about political events with no comments or just stupid small talk posted. You won't be able to tell which are actual government trolls and just corporate-welfare-queen hacks, because they are one of the same. They also do more than just try to discredit information. They also create all these fake organizations and make them look legitimate so you will buy into language about your own cause that makes you look dumber about what you believe. A good example is the overuse of the term "frankenfoods", which is used by a lot of anti-Monsanto activists. They even posed as Ron Paul fans on Occupy Wall St. Facebook pages and made really stupid comments to divide Occupy against Ron Paul fans.
