Yahoo mail should be able to easily recognize spam, as I do. It's not that difficult when it comes from a sender with more than 15, 20, 30, ...characters from domains they won't let you block. Yahoo is endangering the security of my information on my phone and they don't seem to be concerned. Eventually the government will have to get involved. My email is used for personal and business reasons, not some scammer and spammer from all of the world, especially the UK. Stop this easily recognizable SPAM!
