Q Why did Alice fall in love with Bob?
A The author sucks, and the whole plot is stupid.
What should we do with such posts? You must be wondering why do I even ask this question?
That's because "plot hole" can be a legitimate answer to some questions. We can complain all we like about how something is illogical, but on a Q&A site, if "plot hole" is the answer to the question, then we have to accept it. Thus, the above post can be improved by editing out the rant.
Should we edit it/get it edited or flag it like on other SE sites?
Note: I have delibarately avoided giving examples for obvious reasons, but you can easily figure out what I am referring to from the main site.
