Facebook may be hurting their advertisers by showing repeat ads with worsening offers

Delta Airlines is one of several advertisers I've seen on Facebook that showed me the same ad with different (and often worsening) offers.

Today, on 10/7/22, I saw about six ads for Delta cards.

Then the offer got worse!

Okay, it may be a different card, but the advertising algorithm should know that it's already served me similar ads and that I'm going to remember the discrepancy in numbers. Though that doesn't factor in that some people are mindlessly scrolling. Maybe they are the target demographic, because it will affect them subconsciously?

In the end, I decided to hide all ads from Delta because I already have one of their perk cards.
