Whilst I don't believe it will make any difference whatsoever to your
spam levels, it may reduce some load on my keyservers from genuine
indexing so I've added a robots.txt file at the root (covering both port
11371 and 80).

This has been applied to:

pgpkeys.eu
pgpkeys.co.uk



Thanks,

Daniel.

Thank you for heads up, given that robots.txt wasn't previously tracked

Hi robots.txt fan,

I just wondered what happened if I removed robots.txt from my server, to

The real reason is that /pks didn't exist when the robots.txt file was
created, so I've [added it now], granted more for site resource
management reasons than privacy reasons.

From a privacy perspective robots.txt doesn't make sense, the data is
already public, bad actors ignore robots.txt and crawl the site just the
same; and the full data set is available and part of regular workflow
for bootstrapping own servers.

Hello again,

m, thank you very much for installing the file to your server!

Paul, thank you for your kind words.

Robert, this is not a lost cause, but instead a fixable problem. Condolences 
are not required, but a solution is. This solution can only come from admins 
like m.

I have now come up with a larger list of servers that do not yet have an 
efficient robots.txt file or none at all. Kristian, you have responded to this 
thread, I believe you manage the first one on the list. Is there a reason why 
only /status is blocked and not /pks?

https://sks-keyservers.net (blocks /status, but not /pks)

Re: [Sks-devel] Request: Install an efficient robots.txt file

[m]

Hi,

Thanks for pointing this out. I never thought about robots.txt on my keyserver, 
and sure enough, it was missing.

It's easy to add: just drop it in the web/ directory in the skskeyserver 
directory. I did have to reload sks to get it to see the new file. It's now in 
place on gpg.n1zyy.com!

Beyond the privacy implications, I'm also happy to keep search engines from 
performing a ton of 'searches' on my server by following links between signed 
keys!

(And while it's true that _public_ keys are, well, public, I'm happy to not be 
directly giving Google et al. email addresses linked to real names.)

Dear Sirs and Madams,

I would like to thank all of you for doing this. You are a necessary pillar to 
PGP and it is awesome that you are there to provide the infrastructure to host 
everyone's key.

Without attempting to diminish the previous sentence, I have a request to make 
to some of you.

Most of the SKS serve an efficient robots.txt that prevents everyone's 
un-deletable name and email showing up on search engines. However, there are 
some exceptions. I like to keep a low profile, but when searching for my name, 
for example on Google, a significant amount of results are from SKS pages, or 
to be more specific, these:

keyserver.nausch.org
pgp.net.nz
pgp.circl.lu
keyserver.rayservers.com
sks-keyservers.net
keyserver.mattrude.com (special case: blocks /pks, but not /search, a 
non-standard (?) directory)

I would like to ask the owners of these pages to take the time to install an 
efficient robots.txt file, for example something like this:

User-agent: *
Disallow: /pks/

To all others, I would like to ask you to take the time to check if your server 
serves an efficient robots.txt file, and if it does not, to please install one.

If there is any doubt that a robots.txt file is a good idea, I can elaborate on 
that.

Thank you for your time.

Not quite ... each server can decide which keys it want s to accept.

It seems this is the default behaviour, at least when instaled from the
debian package.

It's always useful to hear from a real PGP user for whom this is a real
concern.

My personal priority for the PGP ecosystem is to ensure a pleasant,
unsurprising and privacy respecting experience for all PGP users.

Since you've taken the time to email this list, I assume this is a
reasonably serious issue for you.

We should all be worried about anything that negatively affects the
overall experience of using PGP.

I also support your right to use PGP without publishing your public key.
It's not uncommon for users to have both published and non-published
keys, and we're here to support PGP users, so I'm behind you.

Probably too late now, but you might consider omitting your name
entirely on your key - it's optional. You don't even need an email
address, although that makes life a little tricky for your contacts ;)

Nobody is.  But if you create a public key, then by definition you're
comfortable with it being shared with the public.

If you don't want your public key shared with the public, don't use
asymmetric crypto.

If you didn't generate this key, then please accept my condolences on
some low-life jerk creating a key in your name with your email address
on it and uploading it to the keyservers.  Those people are jerks.
Unfortunately, we have no good way to stop them.

I searched your name (i.e. RTF) with Google and no hits came from

Hi,

how can you assume that it was me who uploaded a key with my name on it?

Please, I try to be optimistic here. This is a problem where I rely on the

Hi,

If you don't want your name to appear on Google, don't upload it to a service 
that permanently spreads it to hundreds of public websites. Especially don't 
rely on every server admin to "block" crawlers from these pages, because this 
fails as long as at least one admin doesn't.

Have a nice day anyway.
