I've encountered this issue while trying to look up nude art models for anatomy references in my art, and I've got to agree it's extremely inconvenient. I was quite surprised by the forced censorship due to the nature of Kagi, and it's very disappointing to see. I don't quite understand what the safe search settings even do since disabling them still censors my results. I believe there is a fine line between "family friendly" and treating the entire userbase as a child in said family. At the end of the day it is up to parents to moderate what their children do online, a safe search gives them the tools to aid in this, but it should not affect everyone else in order to serve a minority.
