valid reasons for this: embarrassment, mistakes, accidental privacy
exposure, etc.
Those are not all the same.
Embarrassment and mistakes are good things. They help us become better
people. What is more likely to help one grow and educate others?
a) One can delete the original statement and pretend it never happened,
potentially erasing with it the reactions of others in the process.
b) One can reply/amend the original statement pointing out the mistake
or change of thinking, thereby positively reacting to potentially
received feedback from others.
accidental privacy exposure
That’s different scenario. On a mailing list there is nothing one can do
to take this back. In fact even with the forum, everyone using it in
mailing list mode or having notifications on a particular thread will
have a copy.
However it makes sense in this case for a moderator to be able to remove
the offending parts of the post.
While it true that threads may loose some continuity, but I think for
troubleshooting people ultimately will only care about the solution
(which is highlighted) and not the whole discussion
See above. Also it diminishes the time and energy others may have
already spent reacting to the now vanished post.
In many cases there are also nuggets of (maybe even unrelated) knowledge
in the replies that aren’t ultimately recognized as the solution. I feel
very strongly about this, as almost everything I know comes from
Fidonet/Usenet and mailing list discussions where helpful strangers
pointed me and others to valuable insights.
We don’t require anyone to register with their real name or identify
themselves in any way here. Everyone should feel free to make mistakes
and even experiment with different ways of thinking. I admit my
sensitivities are triggered here. Ultimately, I see to extremes:
a) A highly censored and moderated “safe” internet with real names and
subject to the whims and fashions of current popular thinking at best
and the will of corporate overlords at worst. It comes with lots of
“code of conduct”, “shadow banning” and self censorship.
b) The internet I grew up in: free, decentralized, messy and edgy but
full of awesome people battling the trolls and idiots of this world with
logic, reason and better ideas. And people like the Qubes OS team
sharing tremendous value with everyone who cares to pay attention.
I’m getting off topic, so I’ll stop myself here.
Also, if users want to nuke their profile, we can also “anonymize”
their accounts. Not sure what it does, though. Probably only replaces
the username on all their posts with “anon”.
I’d rather we state upfront that except for rare cases (privacy
exposure, doxing, illegal content) we don’t delete stuff. It’s out there
anyway (mailing list mode etc).
People don’t have to use their real names and if they feel they
embarrassed themselves so badly they can’t handle it, they may create a
new account and abandon the old one.
