If you noticed a strange user in your WordPress site called "ninukisadm", don't worry. It's a special admin user that it is being used by our support staff to provide support in case of emergency and for general troubleshooting  of your site when you request help. We are also  constantly changing, as a matter of fact every few minutes,  the password of this special user with a new randomly generated password (a password that is impossible to guess) so that we prevent miss-use of this account.
