The primary concern seems to be that commonwealth’s former username would be searchable and lead people here. An easy fix to that would be to put that username in the profanity filter. People could still refer to that username with shorthand that would not have the adverse search effects that commonwealth is concerned about.
I expect that mods will continue to enforce rules against doxxing and harassment. And if someone believes they’ve been doxxed, and that the mods have not addressed it, they can notify me (@spidercrab) and I will remove the personally identifying information.
