But looking at the question page (How to change iframe inner text?), there is no apparent recent activity. The question was posted on 2010/07/26 (it has no edits), and the one answer was posted on the same day (it also has no edits).
This appears to be pure noise that should not be showing up on the "Top Questions" display.
