I had a friend who often said "sunlight is the best disinfectant". Of course, he was saying that in about 2010 and I'm pretty sure it's aged extremely poorly, because the increasing publicity around conspiracy theories has only made them more popular. It feels like a stretch to say "but people were trying to silence the conspiracy theories, that's why they caught on!"
Jezebel wrote an article in 2013 about feeding the trolls until the explode [1]. I disagree today, and it seems quaint. IRL, professional trolls, the Proud Boys, come to my town (Portland) to stir up shit every few years. Do we ignore them? Or do we subscribe to "broken window theory": if they get an inch they'll take a mile? I have a tough time with this, both responses seem correct and wrong at the same time, but there's no way to tell which is working.
The traditional way was to have an eating contest with the troll, where you hide a bag under your shirt, surreptitiously slipping some of the food into that, and at some point pretend to extravagantly cut up your stomach to be able to fit more food, so the ambitious troll will try to do the same.
