We all sometimes have the urge to do or say inappropriate things, no?   A big part of what makes you, you know, you is the degree to which you have a &quot;filter&quot; that screens out those inappropriate urges before they turn into inappropriate actions.<p>This filter is rather different in different situations, because what is appropriate (and what has consequences) is different in different situations.   In a very real way, I would argue that changing that filter enough (and pesudoanonymity is usually &#x27;enough&#x27;) makes you, essentially, a different person.<p>Most people, in a pseudonymous situation,  have much less of a filter, in part because bad behavior is more acceptable, and in part because bad behavior has fewer negative consequences, both to themselves and others, than it does in a real life situation.  (I&#x27;m not saying that there are no consequences;  people are hurt.  But usually not as much as people would be hurt if the same people removed the same filters in real-life interactions.)
