From my read of the “Twitter Files” I hey have multiple levels of ways to reduce a tweets reach. Not allowing a tweet to trend, not show up in Search etc. I believe the “heavy” part refers to how many, and how hard these levers are pulled.
I think it's helpful to emphasize that "Visibility Filtering" and "Shadow Banning" since they are functionally the same thing, but seem to have very different connotations depending on whether the speaker considers the action to be merited. As many on this forum know, one of the oldest and best ways to limit spam or other unwanted user behavior is to hide the content without informing the user, in order to slow down the arms race between bad actors and moderators.
