"moderating" is just a sanitized word for censorship.
and there is no way to censor without infringing on speech and thought, or to do so "fairly".
back in the day, Peegs had posted what wouldn't be allowed, and iirc, it was pretty much limited to personal attacks and using curse words, and maybe bad mouthing the players themselves.
i have no problem with removing posts/replies that are just personal attacks with zero other content, as that would force posters to actually post or reply with some actual content other than just the personal attack, even if the content is only an explanation of why so and so is an idiot communist nazi.
but even then, that's limiting it to just removing the personal attack post, not banning.
once censorship takes place, especially on a political forum, that forum loses what it's original purpose was.
and putting up with all the posts and posters we don't like, is just an absolutely necessary part of having an open forum, and without which, it's just some level of a propaganda site.
