If any of you guys got your articles rejected with the reason "rejected()" it probably got rejected by a bot, I think resending it will work but I still don't know. (thanks to mystery24 for the info) Also, just gotta inform you guys about my article "osu review", I know you guys have seen it many times BUT I've told mystery to reject them since I wanted to improve it. It's the last time I'm going to resend it (if it's accepted of course)
