It depends what the negative feedback was about. If people complained that the product you sold them was poor quality and you're not selling it anymore, you're probably good. If people complained that they woke up in a bathtub full of ice and were missing a kidney, then yes you will get banned, even if the ad is already taken down.
my product is sh*t and i didn't know until i order one lmao.
i'm sure 100% of my customers will complain once received but the ad work so well that i'd like to keep going during 1-2 weeks.
Btw, will they receive a notification to add a feedback after buying my product or a simple mail?
If it's only my ad account it's safe, i could recreate another one.I think people who buy something through Facebook get a notification on Facebook asking them how it went. I don't know exactly what it asks but if people start giving feedback saying your product is garbage they can ban you or disable your ad account.

As well, i don't think more than 10% of the customers will give a feedback on the product, even lower if the customers receive only a mail about it.
