There was quite some excitement when they banned songfics last year, but people are still posting as usual, as far as I can tell. Rules? What rules? Don't they call them guidelines? ^^ Expand your horizons! Write angst to happy clappy songs!

My announcement-post on the matter (http://xsmoonshine.livejournal.com/157181.html). They also banned second person POV around that time, but I don't remember when.

I've had two fics booted off ffnet with no lasting harm - three, actually, but the first was a long time ago and probably doesn't count against me any more.
