I am sorry, but this job announcement seems hocus pocus. I wonder why U.S. people should be interested in that. Yes, sometimes the job situation may be tough, but this doesn't give enough reason to deal with questionable offers. As a minimum risk, there can be a threat of collecting and trading personal data. Maximum risks I don't even want to discuss. So I guess if you feel so really itchy to try earning money online,
buy private proxies so that people won't detect your home address without your consent.
