Allow me to disagree in a couple of your definitions:
Denial means that you are lying. Refusal to answer equates to denial, which means that you are lying. Ignoring all questions on grounds of none of your business equates to lying. The bare fact of using an alt results in accusations of being a so-called “fake newbie”, even when no attempt is made to pretend that one is an actual newbie.
In my view,
Refusal to answer doesn't equates to denial, therefore, I don't see it as lying. I set it as is. Simply don't want to answer, regardless the answer is true or false.
I also don't see the
none of your business equating to lying either! I see it as a matter of privacy and will for not answering! But not implicitely lying!
