I registered on BTC Talk with a Gmail alias address that I've never used for any other purpose, nor have I ever published it anywhere. And, to the best of my knowledge, email addresses aren't visible on our profiles, right? Yet, I just received spam email at my address. So, what's going on? Is the site's database susceptible to having emails scraped? Or is someone selling our email addresses? Or what? Either way, it doesn't look good.
