Here's the deal.
These are newbies, m'kays? Some of them don't even know what the hell a forum is, let alone that this place has rules. Pokecharms could be their first forum ever, and so therefore they tend to act n00bish and stuff. Some of them may have some common sense, and the smarter ones may even be able to avoid warnings. Others are not so fortunate enough to have a brain, and even after constant pestering to read the rules, they still don't get what they're supposed to do. When these newbies to eventually read the rules, they'll usually go like, "Oh my gosh, I've been acting like an idiot this whole time I've been here." But there're still those rebellious by nature, and even after they read the rules they go like pffffft i dun care wut happenz to me lol (yes I fail at chatspeak but you get my point).
I'm speaking from my own experience here, so it may not be accurate but meh. That's what it was like for me; I joined the forums when I was 11 and had no idea what a forum was, and I didn't know this place had rules/where the rules were. But at least I used correct grammar and didn't double-post so I avoided warnings, though looking back at some of my older posts I can really see how much of a n00b I was. I guess I really have evolved a lot. XD
