There's a tricky balancing act here. I agree in general that it's good to not air dirty laundry and I personally would be very unlikely to publicly write something like this about a previous coworker.

At the same time not sharing information widely about a toxic member of your community can create a "missing stair"[0] effect where those with inside info know to steer away from the person. Meanwhile, newcomers to the community don't have that knowledge and end up getting burned.

I don't think there's any perfect solution here. We each have to judge for ourselves where to draw the line between public shaming and the duty to protect others from potential harm.
