Users will be suspended sometimes by the moderator team due to various reasons. But there will be some enthusiastic users who are very much interested to know the reasons behind the suspension of a user. They go forward and post a question on the meta asking "Why user X was suspended?" and all fingers point out to a moderator (some even say that a mod has misused their power.)
There are some reasons shown in their profile page but they are not satisfied by it.
As the suspended user cannot come to meta and answer the question and diamond moderators are said to keep privacy in some matters, there could be chance of wild speculations.
When it comes to user deletion, the user is no longer available to reply to question and the account suspension reasons are a matter between mod and the deleted user. So, there could be many speculations from other users unless a moderator answers.
What should be done with the questions by normal users asking reasons for account suspension and user deletion? Should they be closed? Or should they be answered saying that the reasons to which moderators are allowed to give (which I guess would be the same reason for all the cases)?
