The revelations produced headlines, on-wiki investigations, and temporary blocks of entire congressional IP ranges — the encyclopedia briefly telling the legislature of a superpower to sit in the corner and think about what it did. Conflict-of-interest editing rules were tightened and the affair became a foundational case study in why "who is editing" sometimes matters as much as "what was edited."
