Client Side (Instead of the Dark Side)

It's astonishing how much power there is in simply looking/editing web page source! Possibly anything more seems to get you on the news, so you can stay on the bright side: the client side. Granted, it depends on the contest or website, I guess, but every once in a while you get a gem like this:

answersTxt[3] = "<div id=\"answer-input-3\" class=\"answer-result \"><span></span></div>"; 

answersImg[4] = "<div id=\"answer-final-4\" class=\"contest-answer result hasImage\"><img src=\"/sites/files/bottle.jpg\" alt=\"Picture4\" /></div>"; 

Yes, there's an array called answersTxt[] and answersImg[].

This was a matching game where pictures were matched to text. The administrators have remediated this... they have started hashing the names of the pictures to avoid future shenanigans.
