Is it time to start calling out bad cyclists?

To the guy with really long hair with a hat on, who rides a beat up sunburnt orange fixe that looks like its about to fall apart, who appears from nowhere everyday and RLJ the box junction at Southampton Row and every light to Oxford St. You are the worst cyclist I have ever seen and i am surprised that you have not knocked a pedestrian over or got hit by a bus yet.

I've seen this guy, absolute turd of a cyclist! He's seen one youtube video of couriers in NYC and suddenly thinks he is invincible.

can't wait to laugh in his face when I pass him and he is on the floor
