You should be wishing you never got involved with Pirate .
Theymos wants to avoid releasing unimportant third party information like who had how much invested, that's nobody else's business and won't help anyone. Along with email addresses, account information, other private information, etc.
That kind of stuff would be removed before publicly releasing the pm's.
None of this has anything to do with the SEC though, if they want information or plan to use the pms they won't accept internet redacted versions, they will get a subpoena, get what they want and decide for themselves what's important. So if you are worried about the SEC for whatever reason, there's really nothing we can do for you.
