10 day (in one forum) is 300 a month. Your 5 seconds is more like 30 seconds. That's two hours or more in a month ... in just one of the forums. But that's not the point.
The point is, it's posted in the rules for everyone to read. Some get it, some don't. Those that read it don't have a gripe, those that don't, do.
This is actually one of the more minor jobs in which we engage. We actually spend time reading as many posts as we can ... even participate when we can. And have our own discussions in the Staff Lounge. There's no reason why your inability or refusal to abide by the posted rules (as most do) should take up anyone's time. It just so happens the time to delete a thread is about 10-15 seconds. Deleting a post in one of the Buy, Sell & Trade forums for this infraction is one of the very, very few automatic actions we take. Most actions take some judgement and thought. We spend hours here and sometimes don't delete a single post ... just read. Every day.
