Is it time to start calling out bad cyclists?

Sunny weather means the return of zombie cyclists... nearly got crushed into by one today right in the middle of the junction of Demark Hill and Coldharbour Lane - I was waiting patiently at the red line heading towards Coldharbour Lane (the little round bit where you have to turn into on Denmark Hill if you want to cut through the Coldharbour Lane, I think it's Daneville Road?), as the green light came on, I started peddling with caution as have had a few closed calls with oncoming traffic turning right onto Denmark Hill. Anyway, it was all clear, oncoming driver was patient, as I was near the middle of the junction box, a zombie cyclist came out from nowhere, probably hidden behind some buses or something zoomed into the junction box from my right, so she was coming from Camberwell Green, she looked like she was looking into the void and we were about half a wheel length away from crashing into each other, I shouted "watch where the fuck you are going", she paid no attention and peddled on, luckily due to my awesome balance (this is debatable!), I successfully avoided her, it was close, very close. When I looked back maybe a couple of seconds later, she stopped completely on the side of the road and looked at me with an all too familiar innocent face as if she had no idea what has she done wrong. Well she had only just put my life and quite possibly her life in danger. It's not a big deal, it really isn't darling. Maybe I shouldn't have used the F word, but I was scared for myself and for her. Some people will never learn, will they?
