PowerDNN addresses registration spam issue to protect our customers from DNN registration spam blacklisting

As many customers may be aware, there has been an ongoing issue with fake DNN registration spam for users of DotNetNuke.
The registration spam issue has been an on-again off-again issue with DotNetNuke, and recently it has cropped up even stronger than before. So much so that the DNN experts at PowerDNN wrote a guide on the subject: “How to Prevent / Stop Registration Spam from Fake Accounts in DNN.”
The vast amounts of fake registration spam email being generated by these automated bots targeting DNN sites was becoming so pervasive that many of our customers’ sites were in danger of being blacklisted.
It is imperative to us that we act quickly to ensure that didn’t happen to our customers.
The impacts of having your site blacklisted are severe, and can include: no emails being able to be delivered from your site, your site effectively being listed on a non-trusted or “bad site” list, and other websites in the same environment being impacted as well.
PowerDNN has been proactive from the beginning with the DNN registration spam issue, and we have created and posted news items and KB articles to keep the DNN community informed.
However, we have taken what we believe is a necessary and proportionate response to the problem, by limiting the amount of email being auto-generated in our system. We made changes in order to throttle the amount of confirmation emails being sent to registrants.
This throttling was done to mitigate the amount of spam emails being generated, and to proactively protect our customers and their sites from being blacklisted. All registrations are being performed as normal on all of our customers’ sites, and copies of all emails are being sent to the administrators of those sites.
While this is not ideal, we feel that it is the best available option at this time.
DNN Software has promised a more permanent resolution to the fake DNN registration spam issue, and we trust that they will implement those protective changes as soon as possible. In the meantime, administrators can still send manual emails based on registrations received.
We understand this can be inconvenient, but we know you will appreciate this as the best measure at this time.
If you have any questions, feel free to contact our support team. We will keep you appraised and advised on this rapidly developing issue.
