So you would want men to look up your interests online so they can intentionally deceive you by pretending they like the same things? Even if you don't consider it creepy, it doesn't sound like the basis of a strong relationship.
There's nothing wrong with trying to give someone a good impression, but when you research someone's hobbies so you can feign interest in them, you are starting your relationship off on the wrong foot. If you can't be yourself around someone, then things probably aren't going to work out anyways.
