USCIS and allied agencies responsible for immigration are using information on social networking sites (such as Facebook) to track the activities and postings made by immigration benefits applicants/beneficiaries for evidence of fraudulent activity. While, on principle I agree with deterring fraud, but the "big brother" stance of USCIS is deplorable. Beware folks - big brother is watching. Something you post even in jest may not be that funny in the hands of a govt. officer whose career is dedicated to finding fraud.
