"2015 saw one of my personal email addresses posted on a companies’ Twitter account for six minutes. The account in question had well over 90,000 followers, and unfortunately, it appears a few of those were bots as there has been a noticeable increase in spam on the email address in question since that occurrence.
All the intricate details of this aside, the SpamTitan appliance has kept up to the task and blocked almost all of this spam. In the month following the breach the spam messages hitting the appliance were at a new level of sophistication. Therefore, it took the bayesian filter a few weeks to re-learn and adapt to the style. Since then it has dropped back to the normal levels where I very rarely (if ever) get a spam message that makes it through all the checks."
