1. ADVERTISING
Usually it's a mod; when someone has an elenent idea, Jacob1 or Me4502 (no offense) or somebody pops in and says "They have this in The Powder Sim" or "My mod has this and more."
2. TOPIC DEATH

3. NOOBS WITH STUPID QUESTIONS
"how do i pik an element? pLz hlp!!!1!!!1!!!!!!!!!1!!!!!!!"
4. HATERS
People that hate on other ideas, not just rejecting them, but flaming them. R3APER used to be a hater... (but he's okay)
5. OFF TOPIC POSTS
E.g. Element suggestions on feedback forum.
EDIT: I'm just reding the posts on pages 3 and 4 and laughing.
You guys are unbelievable.
1. It's just so annoying... Mods normally aren't compatible with the official, except yours.
3. I think I posted a way to remedy this, but 2 happened to that thread.
4. There was an element suggestions forum?
5. But nobody ever does hide them...
