Is it time to start calling out bad cyclists?

This morning I saw some epic wtf riding.

I was cycling up Ball's pond road at the junction with Essex road, I was going across the junction in to St Paul's Road towards Highbury corner.

I cycled across the junction in primary and someone on an orange ss or fixed bike overtook me wide, he then proceeded to swing even wider around the right-hand side of the traffic coming from the other direction down St Paul's road and then swung back and continued cycling up the road?!

Saw him too. With headphones and an all matte black bike. We had a chat. Seemed like a pretty chilled out rider. But seemed pretty confident though. Brakeless as well. Yeah Bwoy.
