⚠️ SW-ISAC Advisory
As part of the ongoing monitoring of a coordinated Russian spam campaign, we have identified a number of open registration servers that are either unwilling to act on known spam and coordinated inauthentic behaviour; or are clearly abandoned.
We may make an importable CSV denylist, but for now these domains are listed at https://about.iftas.org/library/known-spam-fediverse-services/#Unmanaged_Unmaintained_Abandoned_Servers for your review.
