I agree, generally I normally lump unofficial information in one of four different categories (keep in mind that this is just how I see things):
 * Headcannon- Creating an explanation to fill in the gaps that the show may have caused based on the rules or information we know. Examples would be creating an explanation for how Ruby and Weiss ended up on the Nevermore or maybe even the fall of the original four kingdoms.
 * Speculation-Using information we already have to try explain certain events or whatever that has already happened.
 * Prediction-Using information from the show to try and guess what will happen in the future.
 * Wild Mass Guessing (WMG)-This one is the most fun and abstract. Normally all it is is people wildly guessing what they think will happen in the future based on very minimal evidence to support their claim. Basically try to predict something without the information to really back it up.

Anyway, these four normally just cover information. I would consider people claiming that one of the character will die as WMG, just shy of fanfiction; but once again this is just my opinion.
