The dexpartacus you mentioned is merely one of the many accounts that have lost funds to this wwefun thief, the same as you. I'm just glad we were able to secure your account again so that your staked HIVE (HP) is safe!
We may never know how wwefun gained access to your account. Accidentally pasting the Active Key into a Memo Field was just an initial guess of mine, but proved not to the cause in your case. Many people lose their accounts by clicking on suspicious links which place malware on their devices, using public WiFi (which is not secure) to login to Hive, logging-in every day with their Master Passwords, etc.
Thank you for blogging about your experience! Hopefully, it will serve as a warning to others to exercise caution with their accounts!
Thanks for the clarification about @dexpartacus! My mistake to place him as a participant, this was due to the heat of the moment and the irritation I felt and the lack of interpretation of account transactions. The hardest thing really right now is to build confidence that my account is safe, and I'll honestly participate more cautiously and less willingly. Insecurity is a very limiting factor. I hope this experience helps others to take care of themselves, really! And thanks again for everything!
