at 21:04GMT on 30/11/2012 I was subjected to at least three adverts on your site which unsolicitedly played sound. The ad units were for Strepsils, Air Wick and one more which I do not recall.
I used the silence button on each ad, but after that ad had finished playing and a new one loaded, the new ad began playing sound.
Please can imgur not use intrusive ads with audio, or make the mute button persistent.
