I look at Switter from time to time.   They announced it was being shut down and provided the following reason

Why did we shut it down?
The introduction and passage of ignorant and misguided anti-sex and anti-LGBTQIA+ policy and legislation around the world has only increased since 2018.

Often confusing, contradictory, vaguely worded, and sold as a mechanism to prevent violence against women and children, legislation such as the Australian Online Safety Act, the EARNIT ACT, and the UK Online Safety Bill fail to acknowledge the realities of what they seek to change or harm reduction and preventive measures, instead relying on surveillance and control.

Despite working tirelessly with human rights organisations to ensure policy makers and legislators understood that there would be a body count attached to their poorly considered actions, Assembly Four was forced to close Switter in March of 2022. You can, and should, read Assembly Four’s full statement on the closure.
