>TL;DR: Where are quests OK, and where are they not OK?

I don't think quest threads should be redirected to one board, just as I don't think all imagedumps, questionnaire threads, or any other type of thread by itself should necessarily be designated to one board. The first and foremost relevant matter should be "does it match the topic of the board" and there I'd add in a little autistic spice in the form of "is it primary or secondary," and then following that "does it break any rules?"

Relevancy can be a tricky topic though, especially on /v/. If a guy makes a thread about his custom-made obese blue-skinned Sim character named Sanic and a guy making a thread where he draws Sanic, and both ask "What ye do?" is there a relevant distinction between them when it comes to rule enforcement? If not, should both be allowed to stay, or should both be removed?

Ultimately I think the easiest and most effective answer is it comes down to the substance and quality of the thread. If the thread acts like a generic roll thread, as in "6 decides XX" then that's a strike against it. If the posts he goes with are "rape the maids" and he draws scandalous images then that resolves itself.
