Since when did all Reddit subs become so heavily censored and monitored?

Dude, I was just trying to post a song in the Black Metal sub and noticed I couldn’t post like 20 different bands. And for what reason? It’s not enough that anything even remotely ideological or critical of the dominant narrative in Western society is already forbidden, now you can’t even post music that indirectly connects to some controversy.

For example: I can’t post anything from Burzum. Fine, I get it, Varg is controversial. But what if I just want to share an instrumental track with barely any lyrics, let alone ideology? Still banned. Same with Mayhem, apparently because they were linked to Burzum negatively back in the day, so that’s enough for a “no-no.” And even Moonspell? Seriously? Because the bassist said something mean decades ago, suddenly the entire band is blacklisted?

What is this? Why is nobody revolting against this online regime?
