I get at the moment a lot of notifications from Defender:
Hi WPjournalist ,
We've just locked out the host 18.104.22.168 from https://www.wpjournalist.nl due to more than 3 404 requests for the file /amp/apple-touch-icon-152x152-precomposed.png. They have been locked out for 300 seconds.
I don't think these are spammers? How can I solve this?
