Email And Anti Spam Why Can't A User Get A Decent Answer From Yahoo Regarding The Anti-spam System On Our Email?

Why can't a user get a decent answer from yahoo regarding the anti-spam system on our email? - email and anti spam

I went to abuse@yahoo.com and support for the e-mail, but received no answer as to why Yahoo e-mail on the Internet continues to enable spam filtering is when the field of e-mails that "assumed" who actually ....... from Yahoo remain on the SMTP server should be intelligent enough to save for the message. Who on Yahoo to read my question and give an answer other than "canned" answer?
