For better or worse, moderation seems to be an ongoing issue on this forum. I think the checkpoint is, whether or not the thread is primarily to 50+ interests. Sometimes the topic is a little murky in that respect and if it's not clear, then yes the moderators move it to something that seems a better fit. Unless there's a violation of a rule, I'd rather see under-moderation than over.
At least when they're moved, we get a link to the new location. I like that, so I can follow it if I want to.
