Thing is, even if Fujino does NOT clarify, the fact it was even implied/confirmed for several things already puts EVERYTHING in the game, even retroactively since part 1, into question. It's no longer Inoda being an amazing NTR dude, it's just God finding the ugly fatso NTR-ing Kirito amusing enough to let him do it. Which...ironically is more 'realistic' than Inoda managing to steal away Yuuki Asuna, funnily enough
This is 100% Fujino's doing so there is nothing to do about it. Administrator didn't even win any polls, her appearance in the game and involvement with the plot were all things/changes decided entirely by Fujino, so this was either his plan from the beginning or something he himself considered would make for a good plot-development.
Like, I myself don't care much, but for those invested in the 'deeper and more complex plot', this is where I'm forced to remind you that Fujino has always been before this game an "insta-corruption/0 effort for the NTR guy to steal and completely turn the girl into a bitch"-kinda 'author', so him doing this is actually...perfectly in-character with him and his work XP
