The most extreme virtue-signal is to go completely browser-default and have no styling whatsoever. Like lowercasing because your pinky can't be arsed to reach for the shift-key even though you've a billion dollars in series A.
I've mostly stopped caring about using using proper capitalization, commas, grammar and spelling in my writing of comments, primarily as a signal that i'm not an llm.
"Countersignaling" (https://en.wikipedia.org/wiki/Countersignaling) might be the better word: "Countersignaling is the behavior in which agents with the highest level of a given property invest less into proving it than individuals with a medium level of the same property."
Virtue-signalling or just the daddy?
Array language proponents also like to do this. In their case I‘ll allow it, it matches the substance.
lowercasing everything -- just means
you're literate smart... poetic; because
you read e.e.cummings
and william carlos
williams
...
