Panzer Solutions is a technical recruiter that sends emails to addresses on resumes that it finds online. In my experience, Panzer Solutions does not honor requests to stop sending these unrequested emails. The 'job offers' they send are also sometimes wildly inappropriate, requiring skills not listed on the resume or advertising posts in locations that are geographically distant from the recipient's actual location (because Panzer Solutions either does not know or does not care where the recipient is located). Searching for keywords such as ***** returns numerous pages from people who are unhappy with email that they have received from this sender.
