What exactly is your position here? In the topic title and your quoted post, you say that you don't need proof, but people might not believe you without it. But as your examples of people "bashing" others for not having proof, you just have people not believing other people, which you claim you think is okay. I have rarely seen anyone say, "You are not allowed to post a drama without proof."
Why are you telling us that we need to believe random strangers who cannot back up their claims?
