The only reliable way to identify mis/disinformation and blatant propaganda is to do your own research, and especially doing so through people who have ongoing first-hand experience with the subject at hand.  In particular, seek out people who are willing to put their (real) names and reputation behind their words as well as show their faces (as in an interview, for instance).  Avoid centralised sources of information as much as possible, especially where that source is a corporation (a large for-profit entity.)  In other words, decentralize your sources of information as much as possible and sample from at least 3 different sources.  Furthermore, avoid large, centralised search engines when doing your research.  Use, for instance, something such as gigablast.com instead.  Often, when using unrestricted search engines, one will find Internet forums that will never show on something such as Google.
