As far as I know, it's impossible to delete accounts. <> Now there are many missed user IDs. Why have they been deleted?

You cant delete your account, but apparently you can ask for it to be "anonymized" by request (see quotes below), or at least you could some time ago.

<...>Some of those profiles have posts associated to them, and apparently, the way they are managed was by tying (don't know it it is physical or logical) them to a "Guest" profile under the generic username "Anonymous" (see https://bitcointalk.org/index.php?topic=15911.msg208900#msg208900 for example), although some still preserved a sort of username (see https://bitcointalk.org/index.php?topic=67541.msg785785#msg785785).

Theres this to go by:

Deleting accounts doesn't mess up any threads, like this thread. It just changes to anonymous, with no profile information. Post stays intact.

As you can see here, I only change the username to "Anonymous" on request.
