I'm only chiming in to let you know that there is no spam problem that can not be resolved. The problem is you are lacking the knowledge of how to.
1. Go to your mail preferences and disable all notifications that you subscribed to.
2. In your unsolicited emails there is an "unsubscribe" button. Use it. It works.
3. After opening a unsolicited email, if there is no "unsubscribe" button, click on the 'Spam' button at the top. This will automatically create a rule for that specific sender and next time his email will go directly to you spam box, which you don't need to open ever.
I would say that 80% of the spam is caused by the settings in your email account, for which is important to follow step 1.
I have a yahoo account and I never receive any spam.
