This was the tail of a flurry of maybe 70 removal confirmations received within a span of 3 or 4 minutes or so.

When I scroll down past them, my mobile gmail client jumps scrolling and return me to view them.

Mailing list removal confirmation notice for mailing list cypherpunks

We have received a request from 185.14.97.176 for the removal of your
email address, "gmkarl@gmail.com" from the
cypherpunks@lists.cpunks.org mailing list.  To confirm that you want
to be removed from this mailing list, simply reply to this message,
keeping the Subject: header intact.  Or visit this web page:

    https://lists.cpunks.org/mailman/confirm/cypherpunks/5db8e755c115cdf1be397adbb8ad45065e984d17


Or include the following line -- and only the following line -- in a
message to cypherpunks-request@lists.cpunks.org:

    confirm 5db8e755c115cdf1be397adbb8ad45065e984d17

Note that simply sending a `reply' to this message should work from
most mail readers, since that usually leaves the Subject: line in the
right form (additional "Re:" text in the Subject: is okay).

If you do not wish to be removed from this list, please simply
disregard this message.  If you think you are being maliciously
removed from the list, or have any other questions, send them to
cypherpunks-owner@lists.cpunks.org.
