The norm is moving. People likely seen more naked then many of there ancestors would have combined. Let alone Solidcenter smut.

Well, "porn" has a very loose definition and varies country by country. IMO it's either nudity (but remember free the nipple movement when you try to define nudity) and/or sexual act usually involving penetration.

Anyway, anyone dancing in a thong isn't even soft-core pornography in my book. Still morally wrong tho in this context.

Victorian ankle showing -> porn

Female moderator showing the weather to be wet soon -> porn

screen unplugged (censored but still) -> porn
