This may sound strange, but theymos may use the Satoshi account to trick people into the tenth anniversary of the forum.
I highly doubt he would do this. And why trick people on the tenth anniversary of bitcointalk? We're six months away from April. Theymos has previously stated that he has not read satoshi's PMs even though he has access to the information. Breaching his account would be a breach of privacy, hardly something to do as a prank.
I don't read PMs for fun. Very very rarely, I need to read PMs for technical, administrative, or legal reasons, but I try to avoid this as much as possible. I don't want to spy on anyone's personal business.
obviously lol, i bet the first thing theymos did when he became admin was to read satoshi's pms.
I've never read Satoshi's PMs.
