I take this Gotham Shield stuff very seriously. May 6th is the 'middle of 7 years' (Dan 9:27) from the Iran Nuclear Deal, Nov 24, 2013. (this isn't the 'real 7 year treaty', but there are multiple layers to prophecy.) This isn't to say that it will definitely happen, they constantly hype things that don't pan out all the time. (When we look at Rev 7, the disaster is stalled until people are sealed, then it is let loose. People are sealed at... Passover, which just ended. That's the context for the North Korea hype right now.
As to why they hype 'conspiracy theories' in such a strange manner, it is not really the 'antichrist' that is the real payload of deception they want to snare people in, it's the false prophet. The false prophet actually will be 'rescuing people' from the antichrist (and yet will enforce worship of a statue of the person that they have just been saved from). So on the one hand, they want to set up their 'bad guy' (the Illuminati or greys or reptilians or whatever), but they don't really want people to be 'awake', they just want there to be a potential awareness of this thing possibly existing. Then when the 'good guy' shows up and 'saves people', it will 'all make sense'.
