Well, I am sure this will make me unpopular.
You have nice set of rules which you are enforcing. Think it might also be worth considering how stack exchange sites are used and who their users are: human beings, most of whom like me do not have accounts until today and do not know the pretty rules. What do we human users do? I will tell you what we do: we look for upvoted answers with the big green tick.
I will also tell you that the person who posted the original question this is about had asked several actual human casual users of SE (including me) how they use the site, because he thought that it was useful to know what humans really do. And they/I told him what we do: see above.
So yes, you may choose to be pure of heart and enforce the rules you invented: that is your choice. You will make (you are making / you have made) the site less useful to its human users, but so be it. Purity of essence is more important, perhaps, than usefulness: I am mathematical physicist and I enjoy playing with pure functional languages, I can appreciate this.
And when you come across a person who believes that how most human beings use the site is more important than the invented rules, however pure they may be, you pronounce yourself baffled of course as you have long forgotten that there users who do not know or care to know the rules and do not follow them: those many silly people who like the big green tick. And so he will decide, eventually, he is more interested in wasting his time elsewhere. Well, you have now driven away someone who perhaps made occasional useful contributions. But again that is your choice to choose purity over utility.
But then, when he has decided he wants nothing to do with this any more, deleted the question (which can do no possible harm as an equivalent question and an identical answer (by him) existed elsewhere) and left the site someone will undelete the question. And then another person will mutilate the question by editing out the part of it which made it clear what he was doing and why he did it. And then this same person will write a public comment which begins:
Utterly obnoxious behaviour from the OP here [...]
I can only suppose that this person wishes to make very, very sure that the original person never, ever returns to stack exchange. That is most certainly what they have done.
Let me summarise this:
- the person posted the question and answer in order to help the humans who use the site and deter conspiracy theorists, after asking several of these human users what they look for when they use the site;
- this behaviour was baffling to some people and so he gave up, deleted the question and answer and left;
- the question and answer were then undeleted for no useful reason;
- the part of the question which explained why he was asking it was then removed by a person, resulting in a question which looks inexplicable;
- this same person then left a comment saying that the person who originally posted the question was being 'utterly obnoxious'.
Or even shorter: person made good-faith attempt to help based on investigation of what humans actually do, ends up having a mutilated version of his deleted question & answer complete with insulting comment sitting on the site.
(1) and (2) are just perhaps a little sad: blind following of invented rules is driving away contributors and making the site less useful to humans. Sad I think but this is your choice to do that.
(3), (4) and (5) are a different matter altogether. I think this is quite offensive and it certainly would seem to be a serious attempt to drive someone away from the site (he already had gone, but he has told me that he certainly will now never return, and in fact wishes he had never joined). If you consider this to be an acceptable thing to do you should think again.
I believe it would be good to consider what site visitors actually do when thinking about questions like this, and remembering that most site visitors neither know the rules nor care about them: they are visiting to get information only. If they like to see the big green tick a lot then perhaps it is worth considering that big green ticks are in fact a useful thing to have, even if they are not so pure. And they do like to see the big green tick: I can tell you this with some authority.
On the other hand the behaviour of whoever undeleted the question, and of the person who mutilated the question and left the comment is simply enormously and I think intentionally offensive. I do not have a recommendation for how to deal with that problem other than to start behaving like decent human beings.
Sadly I do not expect either of these things will happen: this really is the lesson of the internet is it not?
Please note that the person who posted the question is a friend of mine and he has spoken to me of this. However these are my opinions not his: I have not told him I am posting this and I am reasonably sure he will never read it. I may return to read comments but certainly do not intend to participate further here: expect it is rather obvious why.
Also apologise for perhaps unidiomatic English: this is not my first language (not even my second).
