I once asked to change my username. This was done within hours. I once asked for my account to be disabled, if I recall correctly this was done within a day. I asked for it to be re-enabled a year later, and this was done within hours. All of this took a single email every time. I don't know what "Hacker News does not allow users to delete comments"-person wants or what they did or didn't ask at hn@, but it's completely valid to NOT nuke entire threads just because one person has a hissy fit. Reading old Reddit threads (and sometimes even recent Reddit threads) can be a real pain because of this. If they want their content anonymized or their account disabled they can do that easily, if they want some specific post altered or removed then I'm sure Dan will be accommodating.
