Are you having me on? This is just so... I have no idea what to say to this.
If you are looking for a way to harm someone, I am most definitely not the person to ask!

It is most certainly not okay, but you can do so if it's what you want. Of course, now that this is a public post, if something were to happen to this person, they have evidence you were behind it. Your best hope is to wait until things die down, then make your move. Make it seem like an accident. Always best to do it yourself, fewer witnesses.
