I was reviewing some questions from new users, and my inbox button blinked. I clicked on it, to see this :
Leading here.
The problem, is that this comment doesn't exist, I apparently did not commented that post, or my comment was deleted, I don't know : I don't recall having commented that post, and I see no issues with the main post that would have required me to comment on an "issue".
The inbox message appeared the exact same time than the the post was "protected by community".
Although I usually wouldn't care for a notification leading nowhere, here, there's apparently something that I did wrong, but I'm unable to understand what, why or when.
