We have no reason to believe that TINC-Nanopaprika was compromised. Based on our investigation, spam was sent (multiply) on the public (published by members in blogposts, forum topics, event) e-mail addresses.
As an example spam was also sent to e-mails not connected with Nanopaprika members profile. Information from our network system provider NING.com:
Members may have been spammed at an email address that isn't even associated with their profile on http://www.nanopaprika.eu. In fact, I took a look at our support queues and found that we received the exact same spam to one of our public email addresses, copyright(a)ning.com.
You can confirm yourself that copyright(a)ning.com is not a member of http://www.nanopaprika.eu, so it's not possible that this spammer got the email address via your network. We've seen this happen on other networks as well. Unfortunately, there's not much you can do if your members choose to post their email addresses publicly online. You may want to educate your members so they can determine whether or not they should take down their email addresses.
