All auto translaters are limited in their capacity for accuracy. They are ok for single words (usually) and basic sentances, anything more complex can fail miserably XD Due to auto translaters not able to convey the context of the original text, also grammer and sentence structure can be inacuratly translated thus making almost gibberish or translating to mean something different to your original intent.

Being multi-lingual it is kinda funny seeing some of the auto translations into languages I speak XD
