I've just noticed that comments have been removed from this question :
I posted 2 comments, and agree that 1 should have been moved to chat. And not deleted, as I don't believe any academia.stackoverflow rules were broken.
My second comment was a partial reply, which in my opinion only addresses part of the question, and doesn't warrant an answer.
I intentionly split the "discussion" from the valid "comment".
I saw at least 1 other user do this.
Today I notice that all the comments were deleted and not moved to chat.
Isn't this overboard reaction to this question/comments? Did somebody "revenge" flag those "valid" comments?
