On my recent question Does the CDC over-report annual flu deaths in the U.S.?, I have had two comments silently deleted.
The first one, was something explaining the supposed rationale behind the CDC-is-controlled-by-industry conspiracy theories.
The second one was asking "Why was my comment deleted?"
It's not that I really mind having my comments deleted, but I would kind of like to know why they were deleted.
I know there's no hard and fast rule that moderators need to explain all of their actions, but it is certainly encouraged that comment cleanups be explained (at least it was when I became a mod). And it is certainly common courtesy to do so if someone is ASKING why they're being cleaned up.
