You're not alone mate! i have also experienced that so many times especially in social media campaign where some else is using my credentials and earn stakes weekly. It really made me mad and all i did is report the scammer to the manager. If the manager seems to miss your complain, then i fill up a new registration form and put there my complain so the manager can see it in the spreadsheet.
