Rather than just laughing at the problem, perhaps try fixing it? Obvious solution woud be post limits like many other sites use, aswell as limiting unnecessary post by not allowing pointless spam and having tournament/general play session/Nintendo Direct/etc. post in their own threads.
Enforcing what people can and can not do is not the purpose of this thread because this is supposed to be a place where anyone can talk anything about Nintendo. Spam will always be there and people will step in if they get out of hand, but is best to leave it open for what topics people would like to discuss. Something random like what coloured Link is the best (Red is awesome, btw) may seem like random spam to some but it's nice to not feel pressured for what you can and can not post
But given how quite these days are, I don't really have too much of a worry about things getting out of hand to be honest
The fundamental problem is in the nature of the mega thread itself, where posts get buried, even all posts are news related and in 'regulation' A quick fix may be to start anew, but that only is a temporary measure and is quite messy.
I've thought of ways like linking said news in the title to the OP but is pretty time consuming and the OP isn't viewed regularly, as the discussion is at the end of the thread
Thanks for the input though, as ideas are always nice to discuss over
