It would be interesting to see an implementation that lets you view but not interact with removed content. click the spam tag to see all the spam, grayed out. in some cases it might be helpful to know what not to say, or that something has already been said and removed. /r/askhistorians would probably be a place where marking something as removed but visible would not be as at risk of propagating urban legend or bad history. hopefully that community would know what they are getting when they peak beneath the curtain.
