1. People Who Can't Read The Rules These people ask questions such as "Am I allowed to use shaders?" and "Why was my speedrun rejected?" Around 99% of the questions asked on the forum can be answered by simply pressing the "View Rules" on the leaderboards page.

2. "Why my speedrun not get verified???" These people just can't wait for their speedruns to be verified. So, they think it's a good idea to post about it on the forums, thinking that the moderators must have made a mistake. They didn't.

3. Strange Categories These people post about their own categories that they made up. Most of them are just a waste of time. However, there are some pretty good made-up categories that can provide a challenge to DOORS speedrunners.

That's about it. Tell me what you guys think. Add your own little category if you want. This was just my opinion.
