Is it possible to forge forum messages? What mechanism prevents an admin from doing so on this forum, or the silk road forum?

The forums software itself documents post edits, either by user or mod/admin.

You can see the post in question https://bitcointalk.org/index.php?topic=47811.0 is untouched, otherwise the date line would be underlined as in this post which i have edited after posting for demonstration of the function.

The only way to do an edit that is not noticed by the forum software would be by directly modifying the post on the database level.

EDIT: Ok, the function showing that a post was edited doesn't seem to be working as it should. You may now start going paranoid.

Edits are only registered if they are done a few minutes after the time of the post/reply. If SMF works like phpBB those "few minutes" are configured by the administrator.
