I have seen this on the "Unread Topic" screen. It appears to the right of the user names and it is a major eyesore to me as it keeps dragging my attention from the topics to the far right side of the screen.
Glad I use uBlock Origin as it is easy to remove this fluff with a simple Block element command.
But how many more of these are there?
Fixed! Go to the fix.

Not to worry, there's so much going on as well as people getting used to finding things they used to/want to do, never mind the missing things we are still pressing for.
