We can't silence people just because their reactions aren't positive, even if they expressed it already over and over again, so as long it's topic-related it's going to stay. I'm sure most of the members wants to read only positive comments but this is not going to happen in a Linkin Park forum. The band change their musical style every two years and that means people might change their feeling towards the band or the music.
Some of the people here, and in our colleagues communities, are the most passionate people when it comes to Linkin Park. I can realize why some people feels so grumpy when they're getting something that's way too far from what they were expected. Some of the A Thousand Suns reactions were even worse. But all in all people come here to express their feelings - positive AND negative. That is what this place is about.
But I can offer you all this solution: while browsing the site using the desktop you can see a button titled "Report" USE IT everytime you feel someone is going overboard with his comments or spamming just for the sake of it, and we'll address it if needed.
