I got a question by email yesterday from a subscriber who just got this product in the mail. 
Q: Is there any way to prevent ordering from a specific seller in the future, to exclude them, or to know who/where an item came from? I received an item today I really would have loved but the bottle broke in shipping. It was nail polish, so no chance to save it. It was not packaged well for a glass bottle.
I understand if that’s beyond the bot’s code. I still rated it as positive because I don’t want a negative rating to mess up the logic.
A: Good to hear from you! That does sound disappointing.
The best way to prevent the bot from ordering from a specific seller is to give the product a negative rating. It won’t mess up the logic. Negative feedback make the bot a lot less likely to re-buy a particular product. Right now the products aren’t categorized by specific sellers. But it is certainly possible for products to get blacklisted if they get negative feedback.
The product was sold by Chic Beauty, a store on AliExpress.com based in China. The item you got is this one.
This nail polish has been ordered by the bot 14 times so far, gotten 5 positive ratings and no negative ratings. The bot really likes products with 100% positive feedback. If you switch your rating the bot will not buy it nearly as much and hopefully there will be fewer broken bottles in the mail.
