Blocked Senders
Why do you have to hide the block sender button behind a drop-down? The block sender icon should be one of the core icons right after Mark as Spam, at least in the spam folder. Also, lately (last few weeks & 2 mailboxes), when I block senders, it says it deleted them, but they pop back up in the spam folder, and I have to delete them myself.

The best way to get rid of spam is to mark as spam, not delete or block! This helps with your spam filters and does exactly what blocking does, prevents that email from coming to your Inbox. So please keep marking as spam! It is free and part of regular Yahoo Mail. Thanks!
