Where Did the Spambots Go?
Over the past year IndieCommerce websites were having a very bad time with spambots using our webforms or user registration forms to send spam emails. The result was that some Internet service providers were occasionally blacklisting emails from us. This would affect the delivery of order confirmation emails to customers as well as other “transactional emails” that are generated by our system for customers.
To stop the spambots, on June 6, we required all forms on IndieCommerce and IndieLite websites to have a reCaptcha to prove that the “person” submitting a form was indeed human and not a nasty bot abusing our system.
The results from the first month of using reCaptcha are in, and email generated by spambots using IndieCommerce forms is down 35%. Email bounces, which are emails that are sent to email addresses that don’t exist, are down 90%, and “deferrals,” which are emails that are sometimes rejected by the receiving server because they are coming in too fast, are down 90%.
“Bounces and deferrals are both excellent metrics of how happy the rest of the Internet is with us and with the overall spamminess of our messages. The sudden drop in volume is probably all spam. In short, this has made a huge difference, and that will be reflected in our server's reputation and means there is a better chance of all mail going through (to our members).” Josh Harding - ABA System Administrator.
We’re extremely happy with these results and will be updating you as we continue our defense against the spambot menace.
