Cell Phone Email Spam

I have a Yahoo and Gmail as well as an two exchange accounts. I have found that if I press the inbound button then slide the screen down the last email email. Down to the oldest one on my cell phone.  I wait until I see the emails begin to roll in. At the bottom you find the spam. Once I see them I press down on them and then tap the "more" button and mark them as spam. I do this once a day.

The spammers mark them oddly enough using the year 1969.

Thank you and I hope this helps people.
