alright... idk who's the guy but looks like he edit the tittle and info using google translate,
in japanese maid cafe, customers can order a certain maid to do something,
lets say, you enter the maid cafe, maid A greet you behind the door and take you to your seat, give you a menu and take your order,
but then you can order another maid to do a special request, like "hey, i want maid B to write "i love u" on my omuraisu" or "i want maid B to do the spell and dance",
then maid A will call maid B to do the request, and that's what they called a "nomination",
so, the correct tittle translation should be "Sakura-san, you have been nominated!" or "Sakura-san, here comes a nomination for you!",
something like that, and definelly not "I'm nominated for Sakura-san!" since the request didn't come from the speaker.
