When Lauda is giving out negative ratings for being a "liar" and a "troll" who are speaking against him, it sure looks like he is leaving negative ratings in retaliation to speaking out against him.

It's also rather entertaining that you don't go after people doing the exact same thing, especially when you're personally invested in projects that they run. What a coincidink.
