It currently is possible to sneak through with lots of automated translations and "spun" pages. However, I would advise listening to what John Mueller has to say. If those pages begin to rank for competitive keywords, it is very likely they will get a manual review. This may also happen if the number of URLs on a domain suddenly takes a big jump, even though they are not yet ranking or getting a lot of impressions in the search results.
Such a manual review will most likely get your whole site heavily penalized or even completely dropped from the search index.
