I drafted a spec to auto block/show/ask for content previews from specific domain providers. Clients can automatically block previews from a domain, or let the users decide on what to do with it. You can aggregate these lists from different users into a rating system for domains as well. Would appreciate any feedback.

```

{

"kind": 10099,

"content": "",

"tags": [

["d", "domain_lists"], // identifier

["white", "nostr.build"],

["white", "void.cat"],

["black", "malicious-site.net"],

["black", "scam-domain.com"]

["unknown", "ask"] // Options: "load" | "block" | "ask"

]

}

```
