[Outages-discussion] [outages] dns cache flush request

[Jeremy Chadwick]

Despite the Email address and "name" being different, the *exact
same request* (same exact wording) was made in January, only for a
different FQDN:

https://puck.nether.net/pipermail/outages/2015-January/007546.html

My gut tells me that these are likely spammers, or more specifically
companies hired by spammers, signing up in hopes of harvesting
legitimate Email addresses.  (Looking at logs for what IPs did the Email
validation isn't helpful -- these kinds of outfits are all over the
globe).

And probably related: since November I have repeatedly received Emails
from random individuals asking the question "Would you be interested in
Cisco Users list or Industry specific List?", where the content varies
slightly (likely to avoid Bayesian filtering):

 157     11/10 01:24  Alice Smith         (8.9K) Cisco Users
 158     12/03 21:31  Becky Davies        (9.1K) Cisco Users
 159     01/07 07:42  Becky Davies        (9.1K) Cisco Users
 160     01/16 21:43  Jasmine Redmond     ( 12K) Cisco Users
 161     01/24 00:18  Sarah Carter        (6.6K) Cisco users
 162     02/05 05:41  Kitty Bonner        (9.7K) Cisco Users
 163     01/06 23:51  Amanda Brown        ( 15K) Cisco Users List

Welcome to the Internet circa, oh, late 90s.  :(
