This smelled like a hoax from day one. Embarrassing that it was so widely reported actually, people on Reddit were having orgasms about it for a day or two.
No, you did not smell shit (sorry). Russians used their propaganda actors twice and got caught. Do not believe every lie Russian propaganda is spreading.
I don't understand how the audio record was obtained in the first place - I can't imagine the defenders tweeting or sharing it while being attacked by an enemy warship.
I can't find a link offhand, but it was cellphone video from the island, looking out at the warship during the exchange. Not sure why everyone is only using the audio though...
Or it might be deliberate Russian propaganda The Guardian is helping to spreed as useful idiots.
