What's the problem here? He moved an altcoin discussion thread to altcoin discussion board.
Do you see a problem ? theymos should be careful not with their opinion but with them forum rules,Can not someone say bitcoin xt is an altcoin I would like to know if the majority adopted bitcoin xt what will happen to the forum probably the only bitcointalk visitors will be use this forum only for altcoin discussion..
The answer to your question was already linked in the reply above by unamis76, it is regarding reddit but it would apply to this forum as well:
/r/Bitcoin exists to serve Bitcoin. XT will, if/when its hardfork is activated, diverge from Bitcoin and create a separate network/currency. Therefore, it and services that support it should not be allowed on /r/Bitcoin. In the extremely unlikely event that the vast majority of the Bitcoin economy switches to XT and there is a strong perception that XT is the true Bitcoin, then the situation will flip and we should allow only submissions related to XT. In that case, the definition of "Bitcoin" will have changed. It doesn't make sense to support two incompatible networks/currencies -- there's only one Bitcoin, and /r/Bitcoin serves only Bitcoin.
So if the majority of people adopted bitcoin xt then that would "flip" the situation and would mean the "definition of 'Bitcoin' will have changed", which means the forum would then be talking about XT, which at that point in time would just be called Bitcoin.
