Satoshi Nakamoto in very early days and in topic 3, revealed his name and address but that topic was deleted. There is no information that who deleted that thread. My guess is Satoshi Nakamoto deleted it by himself, not by other admins years later.
I have heard people speculate that thread #3 contained some private information about satoshi, but we will never know the truth. As you can see from theymos' post, he isn't sure either. He says that the topic
must have contained satoshi's name and address. He probably never saw the thread either or isn't willing to confirm it in public. I would find it very unusual if someone as privacy-conscious as satoshi posted his name and address on a public forum, but I do believe that it contained some identifiable information, regardless which warranted the deletion.
