In addition to [what Robert Harvey said][1], I'll add the following:

These type of questions (old, massively upvoted, not constructive and out of current scope of Stack Overflow), closed or not, can (and may) be deleted at *any* time.  

If it's old crap that is beyond salvaging and can only be dealt with (given the site's current direction) by deletion, then one should expect that the maximum notification that will be given is **zero/none**.
