It seems to have gone over the heads of some people.
From Erem News:
A Picture of Madonna Flirting with the Jews from the Toilet
The American singer dresses up in strange clothes on the Jewish festival of Purim and published her picture on Instagram.
The global(ly famous) American singer Madonna flirted with her Jewish and Israeli fans with a picture on her personal account on Instagram, dressed up in strange clothes while sitting on the toilet.
...Strangely enough, that image impressed the media, especially the Jewish media, considering it a new idea that reflects the significance of their festival, as she offered her thanks to congratulate them on their holiday.
No, "toilet" was not a mistranslation of "throne."
Other Arab media copied the story as well.
