just because u have to pay doesn't mean it's a scam...it just means they are making you pay for the info
for instance, there are tons of companies that you pay and they'll get you started in Secret Shopping (Mystery Shopping)...however, that's not a scam...you can make a ton of money secret shopping if you want
however, you can find out all the info you need (company list) at
www.volition.com/mystery
so you don't need to pay some company if you can find it for free yourself
i suspect that there is somewhere online that you can find free info on how to do data entry online, but if u can't find it, then it may very well be worth the $50 to you for that information...knowledge is $
