From time to time there are these questions that don't follow the rules layed out in the help section, I'm talking of course about 'off-topic questions'.
Depending on the situation I request to make it on-topic. In case it's too far off-topic or it takes too long, I flag it immediately. However, in my comments I've started to add some direction for where the answer could be found or things that could help them. I'm not sure if this is within the rules of SE, or that I'm just annoying the community by trying to "semi-answer" those questions in the comment section.
