“All” is stretching it, but I think TikTok and the fediverse have definitely attracted significant portions of the progressive left.
What remains on reddit is mostly the liberal left and a few progressives in niche subs.
But if you go to a sub such as r/worldnews, it’s clear that there are no actual progressives commenting on that sub. They either got banned or they left.
Sure, but those are relatively small potatoes.
And if a single person does it a lot, then the tax authorities can easily examine their spending and prove that they are spending more than they are officially earning. And then they can apply punitive measures.
