Stuff along the lines of Luigi-posting. CTH was much more of a proper “all the left” community with everyone from soc dems on up that was largely just filled with anti-establishment shit posters. But, we loved John Brown etc.

It’s actually old hat. Users on r/cth (where hexbear came from) were catching admin bans for upvoting the “wrong” posts years ago.

Explicitly lefty publisher, but the ebooks are DRM free and they include them for free alongside any physical purchases. (They do tag the ebooks with your name and email though.)
