There is a phishing scam hitting many job boards that is hard for us to detect. We're doing our best to moderate and spot them, but the scam starts once you contact them and usually involves a request for a Skype interview, to download a zip file with their 'writing guidelines' or 'payment terms', and to send them an invoice via Paypal. The file is a keystroke logger and they're looking to steal your Paypal credentials. Please see our Tips for Applying Safely Online before applying for any jobs.
Like anything online, please exercise due diligence and caution when applying for jobs and communicating with advertisers you do not know and trust. While we do monitor the job board for suspicious activity and remove obvious scam ads, from time to time scammers can masquerade as employers and send you phishing requests once you reply. Do not download software or open files sent to you by an advertiser or divulge personal or banking details not associated with the advertised work opportunity.
