>An attack on april 18th
There's an associated pdf which is highly suspicious. it says a lot of nonsense.
If the attack does happen, these predictions could be designed to manipulate us, getting us to believe the rest of the things they claim, while they had preknowledge of the attacks.
I don't know if there will be attacks but if there is, don't trust anyone who "predicts" it, as they could just be connected to the people who did it.
