I don't actively monitor this, unless stuff gets through my spam filter - there's a few I notice I'm getting spam from though:
* The NDP party of Canada
* Animal Jam - a mobile game that my daughter wanted to play, and I had to provide them an email address.
* Imgur
* Linkedin
* GitHub (although my github email address is in all my commits, so it's obviously public).
The vast majority of my spam comes from someone named Mya who used my gmail address (I assume by accident) to sign up for a job board. After she did that, my spam exploded.
