It seems that captchas are slow to show of, it is impossible to reach (7,000 code) in 7days. even i worked more, it just too impossible.Also he is a new member, maybe it is his first time to post a job.
Are this kind of jobs reliable? I don't want my work will be wasted
Jobs that require entering captcha are not allowed on oDesk. Also, paying and receiving payments outside of oDesk is a serious violation of the Policies. Please, flag the job posting as fraud.
I wouldn't accept it and I would report it. One sentence stands out. Will tell you payment method after. You will always be paid through oDesk so they should not even be discussing payment method with you.
It's a scam that preys on newbies to the site. They are not newbies themselves, - they just keep posting new accounts. Do not accept any contract and don't do any more work. at best you'l do a lot of work forno money. At worst, you could get kicked off oDesk as well for accepting money outside of oDesk. Flag (report) the job and walk away.
