Ok so I was reading around the internets today and I understood what's the difference between the middle-age prophets and the today ones.
Long times ago, if some guy would say that the apocalypse is near, he would get killed on the same day and all the prophecies would end.
Now there's the internet... if some idiot would think that apocalypse is coming after a few years, he will definitely post it everywhere. And of course, people are gonna believe it. And they don't even know him... How can you believe someone who you've never met in your life, who isn't even your friend? Just because it says he's a "scientist from America"?
Here's a good advice to all the prophets: if you're gonna predict something bad(or good, but that's not very cool), say it's gonna happen in at least a 100 years later. If it's really gonna happen, everyone's gonna remember you as a great prophet. And if it's not gonna happen(most likely), no one is gonna be mad at you, cause you'll be dead. In other words, don't predict something that's gonna happen soon, cause it's gonna be really awkward against everyone when it doesn't happen.
Here's an example: "Famous scientist Benassi-x from Lithuania says: gather your supplies, because on September 16th a great catastrophe will happen. Earth's magnetic pole's will turn around, oceans will flood, sky will turn black and the Sun will tip over to the dark side. And it's all gonna happen on September 16th." See, the sooner the date, the less you want to believe it...
