*note* I'm sure you already realized, but the above three posts are bots pointing you to fake/scam @ home jobs. Which should really already answer your question
Nearly everything out there is fake or a scam. Sorry to say it so bluntly, but I've been actively job hunting for about 2 months now and have seen pretty much everything. Hell, even a lot of outside work are scams or fake.
It really is sad that so many people are trying to scam and benefit off of the unemployed.
There are a FEW honest work at home jobs. The majority of them will be "surveys". It is where you fill out a survey send it in and get money in return. This barely pays any money at all and requires a credit card so I wouldn't suggest it.
The few jobs that legitimate careers working from home usually involve a special education, a LOT of experience, and good contacts. And are a dime in a dozen.
