Currently the instance is the source of unmoderated trolls, and the instance admin seems unwilling to take action despite multiple reports sent.

We’re therefore taking the action of defederating. We’d rather work with the instance admin to keep those trolls in check and minimize the disruption before taking a drastic action like this.

For transparency purpose, you can see which instances we are defederating from by accessing the https://lemmy.ca/instances page and going to the Blocked instances section.
