Quoted from CLEllison:5.) Asking someone to post more pictures on FB resulted in the sellers whining (happened twice) to remove my post because they didn't like that I "politely" mentioned they should ad more pictures and of what.
This caught my eye.
This makes it sound like you are critiquing the ad - you’re not a buyer, just criticizing the ad because it doesn’t live up to your expectations. A buyer would contact the seller privately for any additional photos they wanted, and most sellers would oblige.
