Just a little peeved when people join a casual roleplay and expect it to be two to three paragraph posts for the majority of it. So thry bail because typing out a little more detail is too hard.
The problem Casual has is it's sandwiched between Free and Advanced and there's a lot of players that should be in either of those subforums based on writing skill, comfort level, and expectations. There's a lot of people who don't think they're good enough writers for Advanced (and most definitely are), and a lot of people feel like Free has this stigma that they don't want to be associsted with so they go up to Casual and hit this big learning curve because they aren't used to the structure and expectations.
Because of this, Casual is this giant melting pot both because of it's middle man position and because it by far has the most players; you're bound to get vastly different kinds of players apply for the same game just because they share a subforum.
This kind of becomes an issue when GMs don't firmly set down and enforce their standards because then you end up with players with conflicting writing styles and expectations. You'll have people who write 3-4 paragraphs and expect something similar in turn, only to have someone to reply with half a paragraph, or someone who expects a post once every few days suddenly being thrown into the mix with people who speed post and go back and forth constantly in a day.
So really, the GMs need to write their rules and expectations clearly from the get go and be sure to take more time reviewing character sheets. If you take anyone who applies, you will run into conflicts.
Back when I was GMing in Casual (I was one of those guys who was writing from Advanced standards from the outset but doubted my own writing ability), I ran into waaay more half-assed applications with some ridiculous game breaking stuff than I do in Advanced.
Again, one subforum isn't better than the others, it's what people feel comfortable with. That said, this is where standards pay off to make sure the players are all of a similar level before getting into it.
