What they meant was probably "promiscuous" or in some other form "leading an immoral lifestyle": https://greensdictofslang.com/entry/bzyd5jq
That might make it a bit more plausible why this epithet was removed.
βλαύτη is just a slipper. Not a slipper worn by fops. Not a slipper worn by lesbians. Not a slipper worn by aliens. Just a slipper.
Why do you keep insisting that the Professors are wrong and that this "worn by fops" translation should be retained? Are you an expert in Ancient Greek translation and you're sure they have it wrong?
I'm no expert, but I did study 2 years of full time Greek at uni. I don't specifically about βλαύτη, but I do know that berating effeminate or overly vain men would not be out of character for any Greek author.
Ackcherly, it says "Antiquated and offensive language also gets a makeover." This may be just the antiquated bit, not the offensive one.
