In Revelation is a description of things that will happen in the end times. One of them is the poisoning of a third of the waters. the term "water" sometimes (or often) refers to people/multitudes.
Looking at the mess of a confusion in the information sphere currently anon thinks that about a third of the people/multitudes is misinformed/disinformed - which represents that third of the poisoned waters. (One third has no info at all, one third has somewhat of valid information).
Question everything. At all times.
