It does not surprise me that it is possible to delete all posts by any individual user, a single SQL statement should do. It just surprises me that that is something that this board chooses to do. It occurs to me then that this could also be done by request? If a user wishes to have their entire history on the board deleted a board moderator could comply? Of course that would not rid the board of instances where other users have quoted the individual, but the same applies in this particular case.
