Honestly, I'm kinda split on this topic
On one hand, I would dislike it if I knew someone had a crush on me, then it would just feel really awkward especially since I wouldn't be able to reciprocate those feelings.
On the other hand, it would be good to at least know that there is someone who legitimately enjoys my company, even though I would only be able to like them platonically.
So it would just be really confusing and I'm glad that no one (that I know of) has a crush on me
