Jobs, jobs, jobs

So, I'm unemployed...My goal is to apply to 10 jobs a week, while only applying for ones that I want. This is hard to do. There are plenty out there, but nobody calls me back. The only ones that DO call me back are scams. I totally don't understand how these scams work. But, I really wish they wouldn't waste my time...Or, at least be up front about their scam...or at the VERY least, explain to me how their scam works? Thanks!
