Improve AOL mail by adding a column to the inbox allowing users to block all future mail from the sender's domain IN ONE CLICK
This new column would be a single character wide - very similar to the Flag column or the Trash column:
With a single click, an AOL program can create a line item in the user's Sender Filter (block-mail list). That line item would include the sender's top- and second-level domain (e.g., @spammer.com - with an asterisk before and after the '@'). Users can do this now for themselves under Spam Settings. But AOL can easily automate this tedious work for their billions of users.
Also, this approach would make the new line item accessible to users (in their Spam Settings) to remove in the event of mistake.

Thank you for the feedback.
We are always looking for ways to improve your mail experience and I will forward this information over to our product team.
