I need a word, y'all. It can be either an adjective or a noun/allusion.

I'm firing off an angry E-mail to the editor of our local newspaper. I'm fed up with the typos, not particularly those in the copy (every newspaper commits typos), but the almost-daily ones in the headlines!! Some of these are obviously spell-check generated, and I want to point that out and add that spell check is _____? The word/phrase I want means something that looks innocent or helpful or the surface, but deep down is/can be just the opposite.
