"The network came to life in 2016 in response to some downtime Nekochan was having, and soon became the permanent home for the community at large."
My understanding was that the administrator of Nekochan felt compelled to abide by, and be fully compliant with, GDPR ... and concluded that it was either impossible or too time consuming to achieve.
Rather than expose himself to the (perceived) legal risk, he chose to take Nekochan offline.
Do I have that about right ?
