While I completely respect peoples' opinion on those particular moves, I simply disagree and would cite similar situations in other sports like basketball- It's completely legal to turn into a block out as the ball comes off the board even if it means you undercut someone and will likely cause injury. Crackback blocks are completely legal if they are done above the waist.

I would just like for the governing bodies to acknowledge that it is a questionable tactic that needs to be evaluated.
The open hands are a completely separate issue. They are akin to stepping on feet in boxing and referees need to tighten up their fights by addressing them immediately. The difference between them and stepping on feet is that your foot generally doesn't cut and potentially leave you blind and defenseless.
