@nurinoas To be clear: We propose a search-engine/index that works entirely on the existing mastodon, pleroma, pixelfed etc. It would only index public information! So, no: "hiding from same organisation" is not possible: anyone can use the search anonymously.
Also, to be clear: this is not part of Flockingbird, the software. Just a service for the community to use while we are building this software.
Fosstodon is an English speaking Mastodon instance that is open to anyone who is interested in technology; particularly free & open source software.
