To be honest, I would just ignore it. If you don't give someone any attention, they eventually go away. Believe it or not, posts like this psychologically encourage said behavior. If you really have a problem, don't make a thread. Report it to a moderator.
I totally agree with you sir. Just don't pay attention to those nonsense post and they would go away if someone pays attention. We can't stop those nonsense topic since people have different thoughts either nonsense to other people or not.
