We get a huge amount of spam emails even though we have spam filters and often add entries into an extensive blacklist. Recently we have been getting spam from .click addresses.
Given that they are all promotional spam we have decided to block the complete .click gTLD. They are sold for as low as $1.80 making them attractive to spammers.
The .click gTLD was launched in 2014 but they only began to appear in our email inboxes from this year.
