I trolled those people at school so hard.
Were they your friends or something?
Hell no, they are terrible people.
It's rude to troll people, even if you don't like them. If you don't like a group of people you should just ignore them instead of trying to annoy them.
Why do you even care?
Because I understand what it's like to have someone annoy you for no reason, and I'm sure you do too. There's no reason to go out of your way to annoy someone and you're just going to make them mad by trolling which could lead to other problems. It's best to just ignore them.
