Not the person you are replying to, but I think they meant that the AI needs a substantial amount of either reference (an art genre with lots of samples) or lots of your input if you’re feeding it to rework your concepts. They never said anything about quality.
I would say it’s not necessary if the post is public. I would consider it if it was clear the conversation wasn’t meant to go viral, or if I suspected the person wouldn’t want the extra attention on the platform (for example it’s funny but it’s embarrassing, or maybe I know they don’t fully understand the privacy settings of a post like it happens with some elderly people). It’s a grey area for sure
