I know this community is barely active from how I see it, but this is an account that has always creeped me out, and the fact that I haven’t seen any big-name YouTubers covering it doesn’t make it any better. I tried raising awareness about it elsewhere, but was almost always met with “nah, this channel is bullshit”. I’m not a huge believer in premonitions, but there is just something about the channel that goes far beyond just coincidences.
The channel’s name is Anti-Deception, and has been on YouTube since around 2011. The account is ran by a Christian from India who writes otherwise vague incidents that are about to happen in a certain country, for example murders, natural disasters, protests, etc. And when the certain “event” happens, the person will upload a video stating that a prophecy has been fulfilled. At one point, they uploaded a video demonstrating how a prophecy gets fullfilled from behind the scenes. It might not look like much, until you come across a Tumblr page ran by them that has a list of every single propecy they have written.
You answered it yourself. “Vague incidents”
Anyone can write a vague description of an incident and then in hindsight cherry pick any incident that matches it and claim fulfillment.
