I don't think Ivy was only a beyotch to Michael C., either.
I question how awful someone can be on a reality show and have NONE of it on camera. They basically are filmed if they're awake, dressed, and not in the shower or on the toilet. The producers aren't stupid and they don't hesitate to film ugly. Plus, as cmkwcri said, why go after his construction if you're just annoyed he's an asshat, as that's where you're LEAST likely to get him? Though in Ivy's case, could just be feeling threatened as I could almost sew better than her and I can't sew a straight seam.
I'm going for Austin for the win--I wasn't in the wuzrobbed camp his season, but I loved him on his show with Santino. For that matter Santino really grew on me there, too!
