How many people do you think work out of they're home using a computer and earn from 60.00 to 300.00 ? when I?

put an ad on the internet stating im looking for a job I get these text messages for like pay roll and shiping via ups and placing adds on Craigslist how many of these turn out to be scams and how many are true ? because I have this job where I am placing adds on Craigslist and im making anywhere from 60.00 to 100.00 doing it but I don't know about the other offers yet .until I try them and I am a little to afraid to try the others so from other people's own experiences tell me what you think or know about these other offers I have mentioned and tell me if it is safe or not . Thanks.
