I mostly just decline requests that don't answer the questions.Even if they don’t answer ANY of the questions, the requests still go through (thanks FB).
With regards to location, I pretty much just look at the visible part of their bio to see if they're from my target location before approving.And any information you might want to elicit from the user can be faked (eg: location, whether they went to this particular university etc.).
