RP section. It's on the wrong side of the tracks.
As much I'm sure you enjoyed making that cryptic little statement, I'd like to hear you elaborate on that. I certainly don't recall seeing more than a scant few cases of people misbehaving (biggest of which was one person thread reviving and another double posting) during my last
whole section sweep of every active thread, so if you are going to suggest that there's that much spam then I'm going to have to ask that you point it out to me. ^^
yeah when i see it i will believe it. I already have about 184 members in my group that feel that way and i started it yesterday.
I see no group here and the only one who seems to be complaining about it is you. Would the coalition of the willing please step forward? :D
That being said, worst section...
...well, S&M used to be my stock answer, but they've cleaned up their act since the big trolls moved on to Smogon. Now it's just icky cliques instead.
CQ&F: Always a mess; comes with the territory. It's where all the clueless people and the mini-mods love to go. :\
New Users/Welcome: sorry, but...I find the idea of a sectionful of threads that all amount to the same thing (and x amount of people posting practically identical replies to each) deeply disturbing and my sympathy goes out to Drew for actually having to deal with the inanity.
Other Trivia: The Count To Infinity. That is all I'll say.
ROM Hacking: No offense to the literate, knowledgeable hackers who I know are in there somewhere, but most people I've seen here could do with reading up on basic grammar.
Any given pokémon game section: People - mostly the clueless variety - feel obligated to mention anything and everything here. Many could do with browsing the section before starting a new thread too.
Pokémon General: ...I kind of get the same vibe as from the game sections, really.
...and I think that's it? Listed many because it's hard to call a definite worst.
