Search Results: finding a crush on facebook

Am i the only person who does this? When i have a crush, i like finding out a lot about them so i browse them on instagram and facebook. I even managed to find my crush's parents on instagram. I found out about his two siblings, their names and age, all through social media.

Is this weird and bad? Should i stop?
Do you do it too? I it a normal thing?
What about him, if a guy has a crush on me would they do the same?

Alright, so my crush and his friends found out that I liked him pretty much in the first week of school and then everyone else in the high school started finding out. My crush used to talk quite a bit, but my friends and I annoyed him too much so he stopped talking to me, started talking to me again, and then stopped cause we annoyed him. My friend messaged him a message saying U r so hot and then another one saying U know I love u and then he told me to stop messaging him... but you could tell it wasn't from me and then I messaged him a couple of months after and then he asked me why i was messaging him. His friend messaged me a few months after that and said "Hey x" off my crush's facebook and I replied but then the next day that same friend told me that it wasn't from my crush, that he doesn't really wanna talk to me and if I keep messaging him, it's gonna make him hate me. Hurtful, right? Anyway a couple of people (kinda friends with my crush) told me that it's obvious who my crush likes and that it IS NOT me (it isn't even obvious) and then they told me that he thinks I'm creepy? Anyway, apart from all the sad stuff, I walked into my crush's classroom and him and his two friends looked up at me and then I walked to his teacher and I looked at my crush while I was talking to her and he was FULL ON staring at me and then I walked away and him and his friends started laughing? One of his friends stares at me heaps too... and most of his friends are pretty nice to me. He always stares/glances at me as well... and if he really DID NOT like me, why would everyone tease me in front of him and sort of tease him too? Doesn't really make sense. And whenever I approach him and his friends, he'll go silent. Why would he stare/glance and me so often if he doesn't like me? Thanks for your help!

So I asked a question that said "I like this guy and two days ago his mate (who knows I like him) texted me from the guy I like's facebook and he was like "Hey x" and then I replied but yesterday that same friend of his said that I need to stop messaging the guy, that he doesn't really wanna talk to me and if I keep messaging him he'll hate me. His friend also told me that he was the one who sent the message off my crushes phone. Why did his friend even message me off his facebook in the first place? It's really messing me up. Please help me out? My crush also stares at me quite a bit but if I approach him he'll go quiet?" and I don't think people really got it. My crush told me himself that it wasn't him who sent it AND his friend also told me HIMSELF that it was him (the friend) who sent the message. My crush was also sitting with another one of his friends and when my friends and I walked out off class we must've been talking pretty loud cause they turned and looked at us and then when we were walking past his friend was taking photos of us? And when my crush walked past another time with that friend, his friend yelled out "Hey it's *my name*!" and then they looked at us for a bit while they were walking. If you have ways of finding out if he likes me please write them below!
