Given the your lack of responses to the developer's responding to your
emails, and the fact that all of your original emails were sent in html
format which was rejected by the public mailing lists so no one else
could see them, I'm going to just drop all of these reports as being
something pretty useless.

If you wish to submit future reports, please read the
Documentation/process/researcher-guidelines.rst file on how to do this
properly in a way that will be useful, and be sure to actually respond
to developers who take the time to write back to your reports.

This is not a one-way process.
