My Drupal implementation kept getting spammed into oblivion. I was not able to upgrade – possibly because the site was hacked so I decided to switch to WordPress.
I have not done any posting for more than a year because of the spam. It is really annoying and serves no useful purpose.
Interestingly much of my work in cloud architecture/development is focused on security but like so many other things, it is easier to find time to address security issues at work rather than at home.
