I'm looking for an automatic way to search for an instance that blocks another instance. Instead of manually checking the blocked instances of multiple instances until I find the one that blocks the instance I don't want to see, I'm wondering if there is a more efficient and automated method to identify such instances.
No, I can't. At least not on the client I use.
Maybe consider using a different client?
Or you can just sign into the Voyager website, block the instance, and then go back to your other client.
Which client are you using? I can see the option to block instances in the settings of memmy for iOS
