I've been getting emails from a marketing agency for the past month, looks like they want to sponsor some content on the site. not sure how they got my address instead of the site owners....is anybody else getting these too?

I'm just now new here, but it's no surprise that a site like this will definitely increase the amount of spammish or phishing crud in you mail box. Be vigilant, learn cyber street smarts and don't let yourself be a tasty target.
