Interesting to see that their most important domain, noblogs dot org, seems unaffected.

I think the registrar makes the difference: autistici.org was registered via Gandi, but noblogs.org registrar is Tucows Domains Inc., which points[1] to njal.la, an "offshore" domain hoster that should be more resilient, but isn’t really usable for email hosting, since domains at such a hoster will land on blacklists almost immediately.

It makes no difference when the registry (which is above registrars) is the one taking action.
