Indonesian women have taken a stand against a prominent author, speaker and self-styled cleric who took to Twitter last week declaring that selfies are a sin in Islam - by trolling him with endless selfies.
Siauw has over a million followers on Twitter and describes himself as a person who seeks "the establishment of a sharia-caliphate" and is a "servant of Allah".
But many Indonesian women (and men) didn't agree with him, and have taken to Twitter and Instagram with the hashtag #Selfie4Siauw.
Well played, ladies, well played.
And gentlemen, too.
... and Lord Voldemort.
