We'd better not confuse "disinformation" with "misinformation." "Disinformation" is losing its original, crucial meaning, maybe because it sounds new and cool and precise.

Misinformation is simply mistaken.

Disinformation, though, is intentional and methodical. In other words, lies and other forms of deceit conveyed for a larger purpose.

Mixing the two together, if deliberate, would itself count as "disinformation."
