The thing is sovcits get little bits of truth, exaggerate them, and string a bunch randomly together. For the 45 degree thing, one way to revoke a will in some U.S. states is to clearly write something like VOID on it. To avoid not being clear enough, best practice would be big red letters at an angle across the text. But also, there are easier and more normal ways to void it.

Point bring, I feel somebody saw something like that and took away that red text + angle = get out of jail free. Which, no, that's not how law works.
