I don't know how they got my address, but I first started getting emails, to sign petitions. I didn't mind because I sign petitions on other sites. Today I opened one email (I didn't click on anything) and then after awhile got an email "thank you for signing a petition". I didn't sign anything! I removed myself from their mailing list, not sure they are not going to use my info anymore to sign their petitions.
