I did this earlier with a random post. ROT17 seems retarded, but it definitely generates some text when translated to Georgian. I don't know if any of this should be trusted though, where did this idea originate?
So, has (mirrored+normal) reverse image lookup and rot17/translation been done on all Q posts yet? Wouldn't be hard to automate. My problem with it is the reliance on online services. Maybe not a problem. I don't know if this is worth doing either.
