Someone in Second Life is providing information about another Resident's "real world" life.

[Ayana Auer]

Is it ok for someone to give out another persons real life info in Second Life?

[Lexie Linden]

Nobody in Second Life may distribute any information about another  Resident's "real world" life. You cannot reveal someone's real-world  location ("Bob Avatar lives in Canada"), gender ("Bob Avatar is really a  woman"), religion, appearance, age, marital status, race, sexual  preference, etc. You may not use notecards, textures, chat, IM, forums,  or any other means of violating privacy. Linden Lab will attempt to  delete such privacy-violating content, if possible, and will apply  appropriate discipline.

There are exceptions:

• Information about a Resident contained in the Resident's own profile may be discussed and passed around
• Information that is patently false may be "revealed" ("Bob Avatar lives on Mars")
• Information provided outside of systems controlled by Linden Lab isn't covered by the Terms of Service ("Someone's posting Bob Avatar's address and photograph on their web page")
