all this targeting of social media platforms is a massive waste of time and effort at best, and potentially counterproductive at worst.
reddit is just a dumbed down and retardified version of classic internet forums.
discord is just mumble and irc combined into one easy to use app.
steam is just a video game storefront with basic chat and profile post functionality.
i guarantee you that pressuring, threatening, or cracking down on them will have no meaningful effect on the left, while alienating large amounts of people who use them from your side.
this matters less with reddit since they're basically all shitlibs who already hate you anyway, but steam and discord are just really useful and popular communication tools that are used by basically everybody under the age of 40 (steam) or 30 (discord). if you crack down on them over this shit you're gonna go down in history as the 2020s jack thompson and ruin your popularity with young voters, for virtually no benefit at all. it's fucking brainless.
and even if you stick to fucking with turbo leftoid sites like bluesky and tumblr, it's still worthless. they'll find new platforms way faster than you can close the old ones down, it's not a winnable game for you, just a pointless waste of your time and resources.
you want to hit the left where it hurts, go for their infestation of colleges, universities, public institutions, NGOs, foundations, and media outlets. those are the heart of corruption, from there the vitriol of their ideology seeps out across the whole country, across the whole world even. this is where you need to strike.
