hmm, guys, threatening isn't a good action right?

Lately, lot happened surrounding me.

Someone let an annonymous threatening. As i know, that annonymous threat her by vilify her.
She said that guy disturbed her by making lot calls. And at last that guy use a public phone to call her and wanna cast the blame on her. He slander her that she brought a guy back to her house and they did make love did something [ekem] yea yea, u know i know what's those rubbish f*cker may say. Then i can sure that the girl won't do so. She did explain to me that she is nothing going to do with this problem. She feels irritating and wanna find out who is the mother f*cker. Did he has any family education? How dare he frame the girl? come on, dare then use the materials u got in your hand to threat her by making calls to her parents and threat for money lar. Most pro u can do is just edit the picha and make it like they are "REAL". ahuh, i do hate faker. So, to the annonymous, don't ever think u will success to smear the girl's reputation. U will never be succeed.
Hey, this action is indescribable noob right? To that annonymous again, this world got its laws too. I don't believe those police won't take any action lor. Hmm, for ur information, the girl's family did report to the police. I also wondering who u r. Oh ya, wanna know what's the proves for catch u? u know the girl knows. She also can frame u.

Last but not least, the wise man knows he knows nothing but the fools thinks he knows all.
