I review these things from time to time.  Upon review, OgNasty is provisionally removed from the ban list.  In the past, he has made a meritorious post on one of my self-moderated threads; and as a practical matter, I think that he probably knows more about real-world usage of cryptography than suchmoon does (definitely more than nutildah does!), though that is damning with faint praise.  Therefore, I do not wish to place a prior restraint on his participation in my self-moderated threads—just as long as he does not behave as a total ass with his.

The ban list is not intended to be a list of people whom I distrust and/or dislike, which would be far too long to fit in a forum post.
