The Bain of all of our lives those that use emails is the scourge of spam I think I read somewhere it accounts for 75% of all traffic so why can’t the email providers like yahoo block it. Some do as in Hotmail where you can block delete then click on sweep and never see the same spam twice or the same as in Mail washer where you can delete it or bounce it back as address unknown. I sure that the companies software engineers can do this. I think yahoo is the biggest culprit of letting spam through. Their anti spam programme is just not up to the job. So the only thing yahoo users can do is march with their feet and use Hotmail

However I would suggest if you want to get some thing done about it and put an end to your spam is to write to yahoo at
