There are two listings in the userbase, one for "Mayu Amakura" and one for just "Mayu". The second has no description. The first was the one on earlier today as a hacked account. Except that it didn't take much hacking.
The information in the PMs exchanged says that Maya's player is known to have given out the password to another player. And the player who showed up as Mayu says that he "just found this on my friends pc" and that he's going to change the password.
Does this tell you anything?
(1) Don't give out your passwords to anyone.
(2) Don't leave your passwords on autofill.
If you can't remember something new for each char, pick a set phrase and base it off the char's name: "georgerules" for George, "fredrules" for Fred, etc. Yes, it's chintzy, but it's safer than using autofill.
Since it's not clear that the password was changed, I'll leave it to Mayu's player to contact the Magi (isrpmagi@gmail.com) if s/he can't get into the char and needs us to reset the password to something safe again.
