Try to delete some Spam. Some you can't. Yahoo seems not to care.
I don't know why I even try. I like Yahoo, yet, not so much as to have to put up with more and more spam. I get stupid and lots of " " from PlayXoXo. With no " blocking " you simply can't get rid of it. It says " are you sure you want to delete this folder? " Answer, YES other wise I would not have hit the delete key.

Regarding spam I am at the point of ADDING yahoo mail and website to MY antivirus spam list and have it blocked as when I delete and block spam messages they are still in the spam folder after I have deleted them.

I have been told, " there is nothing we can do." Yet there is something we all can do, LEAVE YAHOO. ! Admin simply don't care. All of our " Ideas to improve Yahoo mail" probably goes directly into their " trash folder. probably NEVER read.
