Long dashes in "shadow-ban–like" is a telltale sign

There is no em-dash in the comment; there is an en-dash used in place of a hyphen where one of the terms joined is itself a hyphenated term.

Edit: Note the parent has since been edited and previously said the tell was an “em-dash”, but now says “long dashes” in reference to a single correct use of the shortest—except in fonts with narrow digits, where the figure dash might be shorter—dash.
