Isn't that more like an authoritarian trait in general rather than a communist one?

As for deleting posts, we've got a new policy indeed where posts that really don't add to threads (for example, fights between users) and make threads turn for the worse are deleted (with explaination - which is visible since a while). However, If you see deleted posts which you think were deleted for a bad reason, or for which insufficient explaination was given, feel free to post a link and a complaint. We should obviously be very careful with deleting posts, and if we're careless somewhere, we're open to (constructive) criticism about it. I myself would not mind some more constructive criticism at all (a problem, I think, is that a lot of criticism levelled at us is generally not helpful or does not argue well).
