Making industry specific NIPs is a mistake.
Same goes for the Medical data NIPs.

For sex workers, focus on WHAT is being transmitted through relays, not WHO.
- Photos
- Videos
- Presumably limited Access Tokens
- Payments
BLOB data like photos and videos or streams etc can be provided by URI as is already done today. The infrastructure to host that is out of scope for Nostr.
Access tokens can be relayed through Direct Encrypted Messages
Payments handled by zaps
Nostr cannot prevent people from being found and won't prevent people from being held accountable in their jurisdictions to whatever laws and regulations they are under.
