I stumbled across a subreddit at one point that I forgot the name of and could never find again. It was a bunch of people pushing memes to crazy right wingers on Facebook encouraging them to do things like not vote and make really poor decisions like tearing up their social security cards.

First, spoof your IP address.

Then, start with Facebook. Create a realistic looking account, preferably with bots for friends, and start sharing and commenting on hateful groups' posts. They'll come out of the woodwork and if you play your cards right you get invited to Discord servers and shit like that where the really heinous stuff happens.

Then, after taking months of screenshots and compiling all the data you can, you turn it over to Unicorn Riot or a similar group and watch the fireworks.

As someone who spent much of her teenage years arguing with various ghouls online, it's not worth it.

Don't, you'll only make them worse

If you intentionally stir the pot and piss them off they'll inevitably just go take it out on someone else and further reinforce their beliefs

Hmmm I would probably try corelating stuff to the woke multicultural agenda. Stuff like being anonymous online, using hygiene products and wearing shoes. Anything that would make them look like a fool or break their stuff. It's kinda hard though because being a white supremacist is already the most embarrassing thing you can be.

Nazis*/white supremacists*

Also don’t waste your time with them

Telegram is full of these groups. Usually, the trolling is simply one-upping their ass-backwards logic, like telling white supremacists to "not even breathe the same air that a non white has breathed! hold it, pass out, but refuse to take any of it in!" - if it's a video of someone stating that and saying there's scientific evidence, people will believe it even more and no, you won't even need to create fake links for said "evidence".

Look around on social media? I mean, they're not exactly subtle, especially now that Elmo runs Xitter.

Join the KKK and troll them in real life!

Film the shenanigans and make a YouTube channel for extra revenue.

You don't need to find them, they find you. Just say something true like "Israel is committing some of the most disgusting war crimes in the modern day" or "Putin is a warmongering asshole". Once you post something like that you get a bunch of idiots reply to you and try to convince you that you're wrong without actually explaining why you're wrong. They just throw strawman arguments and whataboutisms or just straight up lie.
