Part of the sign up process I went through was to copy a line from something Marx wrote (can't remember now I'm a bad communist) to be approved for an account.
Maybe it wasn't like that in the past but it was made clear in the sign up processs that the admins are ML communists and run their instance with those beliefs informing their moderation decisions.
Much appreciated. Haven't found any time to read anything, regrettably, but I have bookmarked your lists!
