I shall explain this as I did in the last thread, and I'm pretty sure the thread before that.
Go Nintendo has a history of posting rumours. Lots of rumours. And yes, in almost every case, they mark rumour reports as just that. The problem is the sourcing of the rumours. Rumours can often be sourced back to a single forum post and/or internet gossip.
Though we encourage new threads for new news, including rumour discussion, we do not support the forum getting clogged up with every single rumour posted on every single website, especially those lacking credibility and proper sourcing. It's one thing to make a thread based on a rumour sourced back to multiple gaming websites with known connections to the industry, and the rumour itself being credible and interesting. It's another thing entirely to make a thread because some guy said some shit on some forum and we believe him just 'because'.
Furthermore, Go Nintendo has, in the past, erroneously reported rumours and information, adding inaccurate conjecture to reports that further complicates the matter. We end up with people not only posting threads based on dumb rumours from unreliable nonsense sources, but ones that could have been easily discredited prior to posting. Or, in worst case examples, the report itself misinterprets the rumour, leading to completely inaccurate 'news'.
This shouldn't be taken as an attack against Go Nintendo. RawMeatCowboy posts here, and is welcome to. His website is an excellent source for all things related to Nintendo. But because of clashes between Go Nintendo reports and GAF's expectations of rumour and news validity, the website was banned. We don't allow 'Chartz for slightly similar inaccuracy reasons.
But, unlike 'Chartz, which has a blanket ban for being full of shit, Go Nintendo isn't strictly banned from discussion or sourcing. You can source back to Go Nintendo, even though the URL will be blanked out. You can discuss news and rumours there. That's fine. We simply express caution in doing so, for the above reasons. This is especially true for making threads. If you make a thread sourced back to Go Nintendo, and the information is reliable and trustwrothy, then fine. If you link to a stupid, dumb rumour with poor sourcing and obvious inaccuracies, then you'll probably get a ban.
Post smart, stay safe. This has been a NeoGAF Nintendo public service announcement.
