We just added (undocumented for now) topic, language, sentiment, and nsfw REQ filter support on filter.nostr.wine. Right now only nostr.wine kind 1 notes are classified. Examples: ["REQ", "topic-test", {"topic": "art"}] ["REQ", "language-test", {"language": "thai"}] ["REQ", "sentiment-test", {"sentiment": "positive"}] ["REQ", "nsfw-test", {"nsfw": true}] * You can also combine them in any way along with traditional filters: ["REQ", "classification-test", {"topic": "art", "language": "japanese", "sentiment": "positive", "since": 1708522116}] *the nsfw classifications are poor and full of false positives atm. migrating that to a new model soon.
