No, it was [[[MSM]]]
Re your tagline: In some groups/sites people use brackets to signal Jews or Jewishness. They don’t mean it as a compliment.
If your tagline was [[[MSM]]] then someone may have complained that you were signaling that the MSM was full of or controlled by Jews.
I can’t be sure that is what the fact was, but it is certainly a possibility.
Some people on the internet use (((insert name here)))to draw attention to the overrepresentation of one particular group among our enemies.
It is therefor often asserted to be racist.
