does cyberbullying actually exist?

i dont want to be the guy that blames the victim but cyberbullying really doesnt make sense to me. i have been bullied in school yes. the thing was that in school the bullies would be where I HAD TO BE. i had to go to the parkinlot to get my bike. and i had to go to cafeteria to get my lunch, and i had to go to the dressing room to swap clothes. there really was almost no other option. so now with more and more news about cyberbullying i just dont understand how it works at all. all net platforms i can think of have a way to mute people, cyberbullying is theoretically impossible.
