I'd like to point out to the admins a trolling attitude not yet prevented by the StackOverflow system:

In the comments below this answer *(link removed since the referenced discussion was removed by a moderator)* ...

* a user suggested a flaw.
* I mentioned that the (possibly flawed) code would still solve the problem at hand.
* He commented that he will down-vote for that.
* I edited my answer - but also pointed out, that he could have done it himself.

In the discussion in the comments thereafter, the user made it very clear, that he was following this way of commenting on purpose to **force** the asker to acknowledge his suggestions.

I was audacious enough to point out to him, that this behaviour is not particularly endorsed here, so he started to delete his comments **and by the same token** citing my comments in his replies, making sure I do not cowardly cover my traces like he does.
