Runs the largest Lemmy instance, for free, for your enjoyment.
Accepts all liability for content, local and federated (there’s little/no legal distinction when you’re essentially running a copy of a remote community)
I’m not in the loop or even involved with LW’s admin affairs, but I would imagine there was a letter or email to them or their service provider that prompted that and likely named those communities specifically. Going out on a limb, I would guess the community removal was a timely response to something like that, and based on LW’s history, an announcement will probably be coming soon-ish.
Before you grab your torches and pitchforks, remember: Pretty much every Lemmy instance is run by volunteers that don’t have legal departments.
