Guys, i think a bad exploit been found on MAL platform (sql injection i believe) so he/she can change any value. Why i dont think its moderator in MAL is, every change a moderator makes gets logged automatically so they could track who it was trying to cause to MAL problems.

In short mean, MAL is hackable (i believe so).
