Just wondering why some moderators feel it's necessary to delete almost an entire page of discussion?

If it's to save space, just send an email that says, "We've deleted everyones posts to save space", not "Reason:Not related to R/C or original topic." Especially in a general discussion thread.

I guess I am speaking for a few of us at once, although I know I have had some posts deleted for what seems to me to be silly reasons.
