This interesting https://tex.stackexchange.com/a/222545/4686 answer was deleted by three community members. I looked in vain for a way to register somewhere my interest in this answer and my vote to undelete it. Is there really no way?
My opinion is that if this community site is to serve a long-term purpose, a chance should be given for perhaps wiser people of the future to ressurect past answers which were in their times not deemed compatible with the then prevailing mood.
update also https://tex.stackexchange.com/a/222610/4686 is a very interesting answer which has been deleted.
update and also https://tex.stackexchange.com/a/222577/4686. (sorry about this one, as pointed out by
Mico this answer was owner-deleted.)
Why all this deletion frenzy? we need freedom of expression, these answers do address the original question.
Why isn't https://tex.stackexchange.com/a/222520/4686 also deleted? what does it put it apart from the previous three I cited?
