This subject was discussed several weeks back (thread title was something like ' Renderosity hacked??? '  

Several members all wtih dedicated rendo emails suddenly started getting spam - I was one.  In around 3 years I never got one single spam message to my rendo email then suddenly it started.

I even deleted that one and created a new and started getting the same to that.

The admins were adamant that email addresses were safe and 'no staff member would ever sell them' despite many protests, and eventually the line was 'it's not us' and the thread was locked.
