If users have a concern or question, they should be able to voice it without fear.
I completely agree, but we are both talking from relatively safe and privileged positions on DT1, and can both be fairly confident that we could raise controversial or unpopular opinions without fearing any real retribution, and certainly not being red tagged by other DT members because of it. As I said, I completely agree that all users
should be able to raise questions or concerns without fear, but the very fact that people continue to hide behind new accounts suggests that not everyone feels this way, and that is something that should be addressed.
Having said all that, anonymous reporting is commonplace throughout the world, in workplaces, colleges and universities, to law enforcement agencies, in healthcare and other public services, and so forth. Although it is regrettable that users feel they have to use alt accounts for some issues, we shouldn't be seeking to restrict their freedom to do so if they so choose.
