SDF is defederated from thelemmy.club. When an SDF user searches specifically for !mildlyinfuriating@thelemmy.club or !Android@thelemmy.club, the search tool gives “no results”.
This is a user-hostile act. Refusing the inform the user is an assault on the user’s dignity. We know the community exists. What happens when the Lemmy server is proactively defederated with is that it will not connect to the defederated node even to check if a community exists. That’s all fair enough. But the user should be informed. Not just that the node is defederated but also the rationale. That’s necessary for respecting the user’s dignity. It’s disrespectful to the user to regard them as unworthy of information.
What should happen
The search tool should respond with:
“Unable to verify the existence of !mildlyinfuriating on thelemmy.club because thelemmy.club is defederated. The reason it is defederated is: ‘the host is mismanaged by pro-Trumper bootlicking nutters’” (for example – whatever the admin wants to enter).
Bonus points for overachievers
It would be extra useful if the Lemmy backend could periodically grab a dataset from a directory service like Lemmyverse. It could then use that information to perform better and give better information. The search tool could then say “the community exists according to our records, but …”

Calm down. Try to make at least one point without using logical fallacy. Not sure why you think I am upset. Where are you getting that from?
