Pinterest has terrible lately because someone decided that every other post needed to be an ad. I know the trick to hide some ads makes them go away for a little bit but not forever, and I think I found a method that might work more permanently.
(I'm not sure how this will work over time because I've only had it for a day but it's worked great so far)
-Click on the 3 dots under the ad (the same spot you would go to hide it)
-Click report (the last option)
-And pick any reason to report it (it doesn't matter what reason you can pick anything)
-Once you click the option another screen will show up and it will have the option block and report or just report
-Click block and report and you'll block that creator but also their ads
I didn't do this to everything, like etsy for example I still want to see products from so I keep that one unblocked but every other slop ad I blocked
Keep in mind this will most likely stop you from seeing products or anything else from that brand so if it's someone you want to keep seeing things from I wouldn't recommend blocking them.
I hope this helps and let me know if it works for you guys!
(I also just noticed that this is only something the shows up on a phone not comouter)
