Hi @Quentin, we have created a post about your account that was stolen, there are links to Hivewatcher discord, if you do not have discord access it is better to create it also there is a link to form to report the abuse on Hive. You also can ask them if it is possible to completely to delete that account but so far I know it is not possible. If you like you can create your account with similar name but very slight change in it so that people can still recognize it
Thank you :)
