The first 3 posts are awfully close together in time, so it just looks a little suspicious - like two people cooperating to pump up the perceived value of some domains.
The good news is that it does not look like one person with multiple accounts. It looks like these are really different people. Justin is even using his real first and last name on the board, and I respect that.
