Showing localised reviews also shows English ones

Problem:
Software center shows reviews in English, even if only localised ones are selected (ie not showing reviews for all languages)

Example: dutch (nl) reviews for nexuiz contain some reviews written in English.

My guess would be that some people mistakenly submit English reviews for their native language. This should be easy to check on the server side.

Proposed solution:
I don't have any statistics on this (server side should have them) but I will assume that the most common error is English translations submitted as another language.

Option one: Spellcheck each review on the client side against English: if it contains less the $threshold misspelled words, pop up a warning to ask the reviewer if she's sure she wants to submit that review for that language, instead of for English.

Option two: Do the same thing, but on the server side. If it passed the threshold, there should be some kind of follow up step to decide what to do with that review. For example have a human look at it to determine if it's really English, and then move the review to the English list.
