You can check on the login logs on that day on June 27, whether http://prntscr.com/l6ppzj logged into the account from another IP address, because I suspect that the account was hacked, because the owner of the sashaabc account did not leave this message. You understand me too, I don’t want to lose my account due to unauthorized access to it. And you also wrote that the same message was left by Boussac http://prntscr.com/l6pqh5 (please check the data, maybe the same person was a member of the sashaabc account and Boussac. I know that on this forum the moderators are good people, and you care about your users, so once again I ask you to check the accuracy of the fact that this message was written by the owner of the sashaabc account. Thanks in advance.
