The Feds had people on 100 user big BBSes.
If you followed the studies about so called “extremism” (which often ignores the extremism of the center) then lemmy played a role in that, so it is more unlikely than likely that Feds wouldn’t be on several lemmy servers.
Thanks for your comment. However that it sits in the high negative numbers (with 3 times the downvotes) shows that this instance is actually a problem. It is quite actively destroying principles of decentralized federated networks. Some very online super posters seem to participate in that.
Again it would be interesting to see who was it that downvoted your post.
