An inordinate amount of pharmacy spam is coming my way from Yahoo.com.

Why aren’t they doing any spam filtering? And if they are, why are they doing what appears to be such a terrible job?

Is it that hard to screen for millions of various nonsense email address variations all carrying the same junk spam message?

The last entity to do this was Hotmail — years ago, I added that domain to my blacklist, and my spam went down tremendously. Yahoo will soon suffer the same fate . . .
