LOL, I don't know. Maybe the creative team was trying to save money? Here's something along the same line. I recall at least three episodes in season six where it seemed to me that Rosalee was wearing the same maternity top (at least I think it was a maternity top). I believe some of those were back to back episodes which made me think the creative team was trying to tell us that at least two of the episodes together amounted to a day in the life, so to speak.
The best way to frustrate a cyberbully is to ignore him.
