How does these spam people get my email address?

I never visit porn sites, or pharmaceutical drug store online.... I never gave my email address out, or bought anything online, or registered with any website. yet I get tons of email spam from them. How did they get my email?? How do I stop it?? I hate abandoning my email address, but this is becoming absurd..

How does these spam people get my email address?
They got professionals. There are many methods.


(1)


For example you are logged on to yahoo and visiting other websites with the same browser. Yahoo sends a small data to check if this other sites is one of theirs so that you dont have to log in again. These people can that small data and cache it ( they were suppose to drop it). later These Professionalz crack and gets your ID by tracing where this came from.


(2)


Brute Ping method. You can check if an email address is available or not with a simple hand built VB program or you can get these type of programs off the net all the time. If its occupied then your ID is added to their mailing list.


(3)


The chain reaction method.


Messenger HCK. This is heavy. Hack in some ones ID using the messenger then get all the email addresses of all the added messenger friends. Use them to get to more e-mail IDs. And so the chain reaction goes on.
