Is she overreacting?

A Internet user called Kim brainless. So, she is about to sue him becasue of defamation. Some people say she is overreacting given that it is a just comment on Internet, which is not important. I don't agree with that since we have been ignoring those comments and the rudeness on Internet is getting serious. The reason he called her brainless is that she said that hands up if you are sleep. What is the matter of this sentence. That's is absolutely natural and there is nothing to take serious or wrong. You might think it is not the worth to consider seriously but we need to set an example for those people who don't care others' feeling and have etiquette.

Hello [이름],  Yes, the proper etiquette over the Internet is getting serious and has to be addressed somehow.
