How to Block a Commercial email address?

How do you block SENDER names in Yahoo! mail? The spammer, Litsa, keeps changing their email address.?

• I receive up to 10 items of spam a day from a SENDER called "Litsa" which alway goes into my Inbox at Yahoo! mail and is not filtered into the spam folder. I can't block this spammer as each item of spam comes with a new email address even though the sender name in unchanged and Yahoo! filters only blocks email addresses. I tried to contact Yahoo! but they sent me in a loop and refused to deal with me unless I was a company trying to send bulk email. And there appears to be no filter for sending Sender names to the trash. Has anyone had any success resolving spam issues like this and if so, how did they do it?
