Spam on e-mail addresses given here has been a problem for years. And I don't mean aggressive/annoying marketing from Renderosity vendors, I mean spam about personality-enlarging devices, little blue pills and counterfeit luxury items. I've changed my mail address (only used here, obviously) a couple times, the problem started again some weeks later.  :-/

I solved the problem in an easy and efficient way: I set up a filtering domain, which only accepts mail from renderosity.com (and subdomains). Any mail sent to that filtering domain not originating from the Renderosity domain goes straight to dev/nul... Since I use this, I get all my purchase confirmations, newsletters and all the relevant stuff, but nothing else...

Now I admit most people can't do this, but their mail client most likely can create a filtering rule like "if it arrives at my Renderosity account mail and is not originating from Renderosity - waste it!". Of course it means you only use that specific mail address here, but anybody halfway internet-savvy uses site-specific mail addresses (just in case they get spammed silly), don't you?
