Spam NFTs aren't just annoying; they're nefarious. 

Since many wallets automatically index and display new NFTs, bad actors can use tracking pixels in the NFT thumbnail metadata to scrape the time and IP address whenever you open your wallet. 

Avoid NFT autodetection!

i believe this is the same issue as auto loading images in email. it’s a thorny issue to solve - directly a convenience vs privacy battle.

yeah, it’s expensive to either serve or proxy the images. someone should just cache ai generated descriptions of the picture and serve it alt-text style 😀

Yes, I spent quite a bit of time thinking about this at a previous job. The default answer is caching the images on your server and providing a cached version to end users, but this incurs storage and data ingress/egress costs that can be significant at scale.
