⚡ What makes this different for AI builders

	Generic Scraping	What this Actor gives you
RLHF Signal	Unranked text blobs	Direct pairing of `question` + `acceptedAnswer` + `topAlternativeAnswers` with exact scores for preference optimization
Clean Formatting	Tangled HTML with scripts	Clean code blocks (`code` and ``` blocks) and clean plain text
Quality Filter	Scrapes low-effort/spam questions	Configurable `minScore` and `acceptedOnly` to extract only golden, human-vetted knowledge
Multi-Domain	Just Stack Overflow	Supports 170+ communities: Math, Cross Validated (Statistics), Server Fault (DevOps), Physics, Ask Ubuntu
