Stolen account holds master password. Is there something that can be done?

The account on question is Hive account@evimeria one of the most active Greek steemians with more followers even than me!

Is there anything I am missing can we stop the heist and reclaim the account? Because as far as my knowledge goes on the matter there is absolutely nothing to be done when the master password changes hands. She probably lost it for ever. All I can do now is go on and flag her to oblivion so the thives won't be using a high level account for plagiarism hurting further steemit in the future.

Any help is appreciated.
