Gmail 'blocking'

I have blocked some spam/phishing emails via Gmail but some reappear suggesting 'unblock sender'.

See attachment.

WTH is going on?

That's just the default Gmail options. It's there in case a legit email goes to spam, so you can put it where you want. All my spam emails have that.

I can understand that - tks. Just get sick and tired of same old spam/phishing emails re-appearing.
