Joanna was excellent. I'm so glad this is getting the airing it deserves.
The twitter rep response was woeful, they know exactly why this is a problem with their platform, why they have done nothing about it and why sex was excluded as a protected characteristic.
I remember them launching the consultation about their hateful conduct policy, I and many other women filled it out explaining that sex must be protected and why it would become a big issue if it wasn't.
They chose to ignore this - I suspect because it clashes with gender/gender identity which they favour above sex as a company and as a platform.
