data entry job sites are a scam. admittedly a very old one as well. i actually fell for an early version of this one back in 2003 when i was home-bound for 6 months. the "data entry" job was really how to become an affiliate marketer using adwords to place ads that i would enter to generate sales for companies.
now that i am self-employed i'll let you in on a fact. i have a virtual team of 1099s that do project work for me. the closest thing to "data entry" is when i pay them for articles they write. but mindless data entry jobs just don't exist. good luck!
