Fediseer represents the kind of horizontalist, agency-distributing creative thinking the fediverse needs to solve its blocklist problems. (It should also be noted that @db0 is collaborating with The Nivenly Foundation on another project, and the reference here to their Fediseer work shouldn't be construed as forming any connection between @db0 and the critique of Nivenly in this thread).
And those problems do need to be solved. As we have noted before, Facebook and its associated operatives are coming for this network. They intend to target weaknesses in the blocklist system to claim that the only possibility for sustainable moderation on the fediverse is corporate-centralized algorithmic surveillance, complete with functionality to auto-report subversive elements to the "appropriate authorities".
