Like I said, people mainly use the drama section to inform others of abusive or immature players. When people come to read drama threads, they are looking for players they can ban so they don't come and terrorize their own server. If someone posts a drama topic about someone without providing any proof of it actually happening, people aren't going to ban the person. Without proof, it would be like banning a guy from your server for doing nothing.
There are actual reasons why people ask for proof if none is provided. I think you are misunderstanding the use of the drama section, because without proof it wouldn't have a use other than for entertainment.
