That is another great thing about Lemmy; Because of slower traffic (due to a smaller user-base), there is always a devils-advocate who comes out of the woodwork and provides a different point of view. I interpret Shit-Finding as someone who will enter a community (or lurk in a community) and perform this role. They don’t (immediately) get dogpiled, so if they have a cogent argument that makes sense, any feedback loops get moderated by the community as a whole.
