Can't expect 13 year old children to be responsible with knives, sweetie.
Nor can the people who run this game control people on the internet anymore than you can. The buttswing action has been around since Impressive Title came out, to my knowledge. Quit acting like an arse just 'cause you're butt-hurt over a bunch of polygons and pixels that were programmed to give the appearance of movement on a computer monitor.
I'm not butthurt at all. I like the dances. I like that we can make dance lines. It's nifty. The thrusting motions weren't necessary, and it's obvious what a bunch of pubescent, horny kids are going to do with it. All I'm doing is suggesting fixing the dances so there's no pelvic thrusting. As for the attitude you're giving me, totally uncalled for.
