Why in the blue hell do you have their names if you never had any legitimate interaction with them?
On a serious note though, from personal experience, if they find you attractive AND they are actually considering you, it's not so bad, but whenever you're caught at a crossroads to do or not do this sort of thing, it's better not to. Sure, fine, cultural norms and society say it's always the girl who should be chased, but you don't have to be a persistent creeper kind of guy. One thing you should remember (and I'm working o too) if you're even just simply trying to meet girls, you have to make them think like they want to meet you. You don't have to be the douchebag player, but yeah, some little Jedi mind tricks here and there are good.
