Now, in case you're not familiar with what 'trolling' really is, I think Wikipedia has a great definition. According to Wikipedia, an internet troll is:

"…a person who sows discord on the Internet by starting arguments or upsetting people, by posting inflammatory, extraneous, or off-topic messages in an online community (such as a newsgroup, forum, chat room, or blog) with the deliberate intent of provoking readers into an emotional response or of otherwise disrupting normal on-topic discussion."

Does this sound like some posts you've seen before? Now, let's be clear: there are tons of internet trolls out there that are absolutely not on the pay roll. Most of these people are genuinely just messing with others to get a laugh, a reaction, or whatever. Not arguing on behalf of multi-billion dollar corporations for up to 8 hours per day.
