Why is spam so irrelevant?

I get like 30 spam emails A DAY! Its probably my fault since I gave my main email to gaming sites but really some of the spam im getting spam like "date singles over 50" and "meet hot blacks in your area" and "COBRA Health Solutions" and "AARP rates low" Like really? im 13! I dont want to date rapist 50 year olds! Im not a frickin senior! Why the hell do I get spam like that if I only sign up for gaming sites! why am i getting spam for old people when im signing up for gaming sites? I get so much spam i cant even use my email anymore! I can't use masonbogert@sbcglobal.net, and now i can't use mason@masonbogert.info any more! wow!
