I keep getting an undesirable ad appearing at the top of my Inbox list of emails, about the People's Postcode Lottery.

Despite having deleted it several times and giving feedback that I find it offensive (this is due to personal religious and moral reasons), and irrelevant to me, the same ad continues to appear there.

What is the point of giving feedback when deleting an ad, if nobody pays any attention ?
