L.D.'s use of fake identities first stemmed from his ridicule of them. He posted various messages on the cypherpunks list with idiotic or paranoid content, anonymously, or signed with silly signatures but posted under his own name. This was his method of parodying the cypherpunk obsession with protecting the secrecy of one's fake names as a critical matter of survival in a dystopian culture; instead he openly flaunted and violated this sacred rule to emphasize his lack of respect for it (or the cypherpunks lack of respect for his objections).
L.D. began to believe that all his opponents wrote the same dull objections, and none were interested in investigating the truth for themselves. He began to satirize them by pre-emptively ridiculing his own posts using their own arguments, leaving them with nothing to say or putting them in the uncomfortable situation of having to agree with one of his own contradictory posts! The initial act was borne in desperation and frustration, but L.D. found the ensuing result strangely compelling, even satisfying, based on confused onlooker's responses. "Why is this person arguing with his own posts? Are there multiple people posting through this address?" This speculation reached a crescendo with his email@example.com account as some thought it was a remailer address.
Eventually, L.D. began to focus on developing what he clearly began to treat as a cyberspatial performance art form: manufacturing entire threads on a subject, complete with an array of characters all interacting with each other and having distinct personalities. This was all aimed not at improving his own reputation, which has reached legendary levels of notoriety and insanity, but at drawing public attention to a controversial issue by creating the equivalent of a twisted spectacle. He delights in posting in high-traffic newsgroups, and crossposting to ridiculous extremes. In short, he's an agitator, a provacateur, often for causes he alone grasps.
In many ways, L.D. invented a highly personalized and stylized version of what is now known as a "troll," except that his version usually masked meaningful and significant ulterior messages, sometimes several layers-- with a structural complexity suggestive of a radical new form of the classic literary allegory. His favorite target are Orwellian overtures by the government, particularly in the NSA. But he always tops it all off with what is known in Shakespearean drama as "comic relief".
L.D. fades into the woodwork whenever the world is humming smoothly along, and emerges out onto the stage of cyberspace whenever reverberating turmoil is generated from a public controversy. He particularly excels in satirizing individuals as representatives of the ideas they hold. So, not surprisingly, one of the few vocal public advocates of Clipper, Dorothy Denning, has been subject to some deep gashes from his poison pen.
But at times L.D. appears to be attracted to satirizing anyone that fits the profile of having a big ego, public reputation, strong views, and yet avoids the public spotlight or close scrutiny, possibly feeling above reproach. It is reminiscent of the style of guerilla warfare in the realm of reputations, wherein the fighter with nothing to lose strikes, more symbolically than effectively, at a public target, more for emotional than physical impact-- the way in which the buzzing of gnat can be enough to momentarily distract even the largest and most powerful animals. One of L.D.'s favorite Tao-like sayings is that "sometimes you lose by winning and win by losing".
