Dang, I actually thought you were doing a great job. I try to keep a playful tone when pointing out corrections so people know I'm not just trying to bash on their mistakes. Sorry if I made you feel otherwise.
note: if someone's doing a bad job, I won't bother pointing out corrections. A good translation is worth the effort to fix a few small mistakes, but fixing a bad translation takes so much effort you're basically taking over the work of the scanlation team.
