I REALLY DON'T KNOW WHAT SHOULD I DO WITH TROLLING ON PURPOSE

You try to ignore it. And then report it afterwards.

The DEFINITION of someone trolling is that they do something for the purpose of making you upset. Once you act out and get frustrated, they've won. Their goal is to make you upset and angry at them. That's why you try your best to ignore trolls.

The reason is seems like trolls don't get banned (they do, but it's not an automatic system like the chat system) is because everyone and their mother and little dog, too, are yelling about trolls, and many of them aren't. Banning trolls is like a Where's Waldo book. Seeking out the trolls in a sea of chaos and noise.
