Basically what the title says! I liked the blank space under my profile before earning it and I dislike the clutter of having a badge there now. Also I feel like having the bronze badge always visible makes me feel pressured to or more competitive about having posted on the forums so much, which is a mindset that I personally want to avoid altogether.
My suggestion is that we should be able to set our forum messages to have no badge showing! A simple "No Badge" or "Default" (taking after the profile decoration section) would be much appreciated, and since it's a totally optional feature that wouldn't affect the people who want to have their badges visible. It could also be helpful if we received a congratulations notification when we crossed the threshold for the badges to be available, since if this was in place the badges (ideally) wouldn't immediately appear next to your messages without informing the user.
