I'll give a comment. I think the editor will give a more in-depth comment on this.
We started to highlight some these issues around the Johann Hari case, which came up just before this publication, and we have stressed certain issues that we think are incredibly important that might not have been clear before. This was the position we took when we put the code of conduct together. I think we still hold it, but I think the editor can probably enlarge on that.
