2) At point point were they viewed without my consent?
Only theymos and Gavin can view PMs. Gavin doesn't really do any forum work (he's mostly an admin in case of an emergency, these days, although he used to be the primary admin), so it's unlikely that he'd bother. Theymos only does it in the case where we need to verify a PM quoted by someone in a scam investigation wasn't modified or other such extreme cases.
Nothing happened. I just wanted this documented.
Only me, Gavin, Satoshi, and Sirius are supposed to be able to access the database directly, which is required for reading PMs. MagicalTux and anyone else with access to the server (hosting staff, etc.) could technically read PMs, though they shouldn't.
Probably never.
Ok, thank you.
