How does that happen? I know that "googlebombing" google translate used to be a thing as i have seen it done fairly often(usually stuff like translating android to iphone etc) in the Danish/English translator, where the fact that a few votes could change a words meaning. I wondering if what happened here is a less harmless version of that were a group of people deliberately messing with crowd sourced translation tools, and if facebook have any kind of sanity checking on their translate function or if they are as vulnerable as google translate to that kind of manipulation?
