You can now hide your own bug and question comments. If you want to hide a comment made in error, you can use the “Hide comment” action.
You can see it, and even unhide it if you choose. The project’s maintainer or the trusted people delegated to work with private information can still see your comment.
This allows you, or the people the project shares private information with, to hide just the comments that contain personal information. The bug does not need to be made private if the comment can be hidden. Project maintainers can also hide comments because they contain spam or abuse.
