+1 to the anon who used the "username2" account to post the parent comment. IIRC, there was an original "username" account, the use of which of collectively discontinued several months ago because its value to the community was co-opted by abusive anonymous users logging into it. I would hate to see that happen a second time, to "username2". If it were to happen a second time, that would disincentivize necessary, honest, and respectful use of the anonymous account. If that became the norm, even if there were a "username3", the perception might become there isn't a general anonymous account on LessWrong for users. If people stopped trusting the resource completely, that would be sad. Also, it might send the signal to disrespectful anonymous users they can make or use as many anonymous accounts as they want, and the moderators would do little or nothing to stop them. This last point strikes me as unlikely, though, especially if LW mods have the power to block specific IP addresses.
