I just went and took a look at what happened. To be honest, Rookies are meant to be the charity games, not Frookies. That alone is weird. But, still, that jackass who "accidentally" nominated you is nothing but a fake and a liar. You don't "accidentally" nominate someone. You have to click on which two people you want, and THEN click on "save". So, yeah, it was no accident. It was clear he wanted to ruin it and didn't care what you were trying to do. It's people like him that are selfish and awful. Sorry it happened.
