I kept getting humans evading my CAPATCHA and sending me marketing SPAM
through my web site's contact form. After a while, I would just go
through the web long and find the IP address that completed the form and
block the entire subnet. So far, entire swaths of China, South America,
and Russia can't view my site. Their connection is refused based on
their IP address.
A broad brush, I know, but I haven't had any marketing emails to improve
my SEO score, improve my site, or better my mortgage interest rate.
