The title sounds overly negative but idk how else to ask. Is there a list of known conservative / corporate owned / generally shady Mastodon instances that I can block outright? I don't want to go searching for them, but I also don't want to stumble upon posts from them either, so I'd appreciate a list of confirmed shitty servers to essentially copy and paste.

Some servers have their list of moderated servers made public, visible on the about page, might be worth checking some around

I'm sorry, are you talking about pawb.social? That's the Lemmy instance I'm on and I've never heard anything particularly bad so please show me what I'm missing. Of it's my Mastodon, I'm on bark.lgbt over there, which has no bad history from what I know.
