No, I don't agree with you.
Is has been thrashed out several times in Site Issues (the right topic and one which MNHQ routinely reads and responds to). I've reported this thread, so they can see it and comment on it if they wish.
Funny spoof threads I like to see stay. But they don't always.
Because anything that seems like trolling goes, and I think it's utterly correct that it does. In all topics.
If someone asks for real, then they will get the same responses and it will be helpful to them. It's nit as if there's any shibboleth on MN about starting multiple threads on the same topic.
But there is one on posts/posters which break talk guidelines.
If you think those guidelines are wrong, it is a debate which needs to be had where MNHQ can see it, and in a topic which has lots of traffic (perhaps stickied in active).
What there won't be is different thresholds for trolling in different topics. Unless you actually want to attract trolls (whose aim never is to provide a useful platform, but rather to disrupt) to those parts of MN.
