Just a few observations I made while frequenting the forums.
#1 A person who was hated in their highschool is in all likelihood among the most popular posters on the BBS.
#2 BBS users in general hate people who steal others work, but have no compunction using "STFU" and "O RLY" pictures over and over, obviously designed by another person.
#3 Foreign users can vehemently voice their hatred for the US and everything american, while using every feature of Newgrounds without second thought.
#4 Atheists make more topics about christianity(if only to bitch about it) than christians themselves.
#5 BBS users say noob less than 40% of any other forum.
#6 Most haters of Eric Bauman on the BBS don't actually know his site's name.
#7 Most emo haters don't know why they hate emos.
#8 Shitty, overrated flashes can spawn various topics in less than an hour on the BBS.
#9 85% of BBS users are fifteen and have a voice of credibility on the forums.
#10 A person who makes a goatse flash that incorporates a virus won't have their account deleted. A person who disses the button layout will have their account deleted.
#11 Posting racial slurs is higher up on the BBS rules of not to do than talking about hacking and piracy.
#12 Every user claims to hate Fred Phelps, but will call you gay in their next post if you dare contradict them.
#13 A person can claim how much they hate Wade or Tom Fulp, but whenever either makes a topic you can expect the same user will kiss their ass.
#14 Attention whores are generally frowned upon and will typically have their thread locked, but a well-known user can make a topic telling the BBS to photoshop their pictures and have the thread reach fourteen pages.
#15 More people on the BBS like Greenday more than they like Led Zepplin.
#16 Naruto has a greater fan base on the BBS than John Wayne.
#17 BBS user claim "I'm Rick James, bitch!" is cliche, but will post South Park and Carlos Mencia quotes at the drop of a hat.
#18 There's more sex fictions on the BBS than BBS users.
#19 It's okay to have "Communist, soviet, marxist" in your name, but not nazi or SS.
#20 People menstrate about Bigbadron being a hardass, despite he hasn't handed out the majority of bans(from my knowledge).
A couple I can think of off the top of my head.
