Because I don't value my time, but also because of curiosity, I counted all requests in this thread and classified them. Here they are, from the most numerous to the least.
1. Coombrain tier - 38 requests - no surprise here, the threads are dominated by coom.
2. Fine tier - 26 requests - I was surprised these came in second, seems like there's actually a decent amount of stuff to draw. Drawfags, me included, might be a bit too picky.
3. Passable tier - 21 requests - these can be either fine or shit depending on your opinion. They are usually a bit weird, annoying or hard to draw. Many of those are recurring too.
4. Draw X wearing/doing what Y does ^_^ - 20 requests - I personally hate these so I put them in their own category. Quite a lot of them, you people have "impressive" imagination.
5. Shit tier - 13 requests - actually repulsive. At least half of these is the guro spammer, I haven't counted exactly.
So, the state of these threads is bad but not as bad as I thought. It will probably get worse with time though, as it's been doing for years now.
