What is the nature of the forum? Is the quality post the most important? In my opinion, if a forum is full of quality posts, then it becomes a scientific journal. The forum I like is an easy discussion environment.
I have been here for almost a year only but the true nature of this forum has been ruined by those spammers and shitposters. In reality, we know that forum is a place for discussions and place where we can learn. I don't say that Bitcointalk's nature has been lost already. Its just ruined because of this stupid spammers who post nonsense and useless posts in this forum.
