I don't know about sticks up their asses but I also get frustrated when threads are closed. If a thread is sourcing or something clearly violating rules, that's one thing. But sometimes they're closed because a mod thinks they're unnecessary, and I agree with the previous comment to let the users make that decision. If no one sees fit to reply the thread will die on its own, and doesn't need to be closed.
Another example is
http://www.bluelight.ru/vb/showthread.php?t=554607. I knew the answer to this guy's question. They were banned with caffeine, so the company retooled to make them without caffeine, and now they're back on the shelves. But the thread was closed already, so I wasn't able to post the answer. I PM'd the answer to the OP and he was grateful to find out.
You could argue that alcohol is not an "other drug" but where should alcohol questions be posted then? It is natural to scan down the forum list - "not ecstasy, not cannabis, not steroid, not psychedelics, so it goes in other drugs." If OD isn't supposed to be that kind of catch-all then it should be placed in a different part of the forum list.
