It seems to me that the logical thing would be to not use your personal e-mail for such things like public mailing lists, including ones like the Debian bug reports, there are literally 100's of e-mail services that are free, and designed for temporary use, that be part of the reason they exist, so that people can use them instead of a private, personal e-mail address, or the company e-mail address.
Did you not notice, when you first looked at the bug reports list, it is pretty obvious, all the e-mail addresses are shown, if this was going to be a problem for you, why didn't you use a temporary alternative e-mail ?
And here it states pretty clearly:
https://www.debian.org/legal/privacyMailing Lists (lists.debian.org)
Mailing lists are the primary communication mechanism of the Debian Project. Almost all of the mailing lists related to the project are open, and thus available for anyone to read and/or post to. All lists are also archived; for public lists this means in a web accessible manner. This fulfils the project commitment to transparency, and aids with helping our users and developers understand what is happening in the project, or understand the historical reasons for certain aspects of the project. Due to the nature of email these archives will therefore potentially hold personal information, such as names and email addresses.
There also are easy ways to make the header show a different e-mail address, one that is fake,
from;
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=907199--email=ADDRESS
Set the email address your report should appear to be sent from (i.e. the address that appears in the From header). This should be the actual Internet email address on its own (i.e. without a real name or comment part, like
foo@example.com). This setting will override the EMAIL and DEBEMAIL environment variables, but not REPORTBUGEMAIL.
Simple rule of thumb, If you do not want your e-mail shown to the public, do not post it on public lists, and mail lists, and forums as well for that matter.
The point is that you NEVER go public with other people's email adresse, or any other private data
for that matter, especially if you don't have any reason to to do it and it doesn't serve any purpose, which is doesn't in this case.
If you want to write to someone, it should be done through the forum-site. I know the report site is not a forum-like-site, but it should be! O
No body went public with your e-mail address, YOU went public with it when you posted it in a public list. Occasionally we get some members that actually do that here as well, and include their e-mail address in a post, ...Try using some simple logic, and have a good day.
