survey-for-cash sites (am I dumb for doing this?)

So yes, like I said I am bored out of my skull. I was looking at my facebook (which I do obsessively lately, looking for friends to chat up and do something) and there was this ad for 'did you like the movie memento?' and some sort of survey so I clicked it and checked it out. 5 questions:
1) who was your favorite character: [teddy] because Joe Pantoliano is always amazing.
2) how many times have you seen the movie: [4] I think. One of my most watched movies, perhaps second only to The Professional.
3) Did you like it better than The Shining?: [yes] only because I have only seen the TV edited versions anyway.
4) do you think it is appropriate for children under 13: [no] ... watch the movie...
That may have been it, then I clicked the link and it asked me for information to receive $10 - $20
for taking the survey from some site called survey4money or something like that.
Rather than immediately giving my information, I opened up a few new windows and looked up the site on Google to see if it was legit. I got back a lot of red flags so I just shut the window and said screw it.

But then I got to thinking: Are there any legit sites out there?
I am bored, I am not working nearly as much as I'd like to , what if one of those survey sites are real and I can make a couple of buck on the side that is time-consuming (because right now all my time is good for is consuming).

I found a few general 'review survey sites' sites. They seemed pretty okay and they all mentioned one site, www.PaidSurveysEtc.com as being pretty good. I am always extremely skeptical so I looked at more places. Scammer-alert also seemed okay as well, looking at several types of scam sites. I was about to give it a try. The site required a membership fee, however. 34.99, one-time which was half-off their normal fee with a coupon code! holy crap! That's what set me off though. I remeber seeing the coupon code in one of the previous sites I looked at (can't find it again) and it was published last February. PaidSurveys was saying that the coupon was reinstated three days ago and was expiring three days from then (today, wouldn't you know it!)

so I looked at the source code of the site not expecting really find anything; I only took an intro computer programming and and intro to HTML in high school and that was about 8 years ago (God I feel old). But it happen to stumble onto something.
every instance of of the dat 3 days ago was shown as:

<script language="javascript">document.write(vStr);script>

I used find to look up documet.write and it came up with all of the instances of the date. Then I searched for vStr and I found what I was hoping to find:

<script language="javascript">
 var montharray=new Array("January","February","March","April","May","June","July","August","September","October","November","December")
 var todayDate=new Date();
 todayDate.setDate(todayDate.getDate()-3) ;
 //alert(todayDate);
 var vyear=todayDate.getYear();
 if (vyear <>
 var vday=todayDate.getDate();
 if (vday<10) vday="0">
 var vmonth=todayDate.getMonth();
 vStr = montharray[vmonth] + ' ' + vday + ', ' + vyear;

this does what you expect it to do, find today's date, set it to 3 days ago and make it so it can be printed wherever it need to be.

Anyone who knows about HTML writing and such would be able to find this stuff pretty simply, I just thought it was a somewhat cool discovery for me.

I guess I made this post in the hopes that someone looking up the site will find this and they won't get scammed.

Now I need a better idea of what to do with my summer....
