Other nonsense? As in viewpoints that are disagreeable to the moderators in charge?
There’s a clear difference between male enhancement spam and a guy with a poorly thought out comment that most people find disagreeable. A middle schooler can spot the difference.
Back in my day we welcomed those poorly reasoned or flat out wrong comments: you would attack them with logic and use them as opportunities to find the truth of a matter. And the community reading it would revise their priors and the needle would move closer to the truth.
Today those comments get censored, leading to much of the awful discourse you see on FB and Reddit these days. You can’t discuss sacred cows without getting banned from a community or shadowbanned altogether.
The ridiculous rhetoric on the left these days is a direct result if this phenomenon.
