In my opinion, the reports had the effect of informing not only the lobbyist who was the subject of the report, but also other lobbyists, of the obligation to comply with the principles and rules of the code, as those reports result in bad publicity. It's not much, but there are articles on the topic in the media for a few days.
In my opinion, it really is a useful way of informing lobbyists, public office holders, and the general public.
