Would they remove my ads if they dont get enough clicks, even if no one else is bidding on these keywords?
Yes, this can happen, but not simply because there are too few clicks. Actually, it is the ratio of impressions to clicks (otherwise known as CTR) that matters.
Because there are many possible explanations as to why your ads are not appearing, it'd be best to have AdWords support take a look at your actual account if eWhispers excellent list doesn't turn up the cause.
