The troll effect
When somebody on the internet starts trolling in a comment thread, it often elicits more people to come and troll (for the lulz). The larger the "troll train", the more trolls it will attract. This is known as the troll effect.
User 1: Wow! It's so nice to see another rover on mars!
User 2 (in reply to User 1): Bet they didn't tell you that the footage was all recorded in a studio!!
User 3 (in reply to User 2): Shhhh!! Brainwashed people are sensitive to these truths. Careful with what you say ;)
User 4: This is obviously all fake. I call BS.
User 5: You guys really believe that this is real? lmao
User 6: Can you trolls just shut the fuck up? You're only amplifying the troll effect.
