Domains to block incoming emails from

[Garacesh]

Anyone got a URL blacklist they can dump for incoming emails?

 

The obvious ones spring to mind, social networks (facebook, snapchat, tiktok etc) and purveyors/aggregators of adult content, but there's bound to be tonnes I'd miss.

 

I know it's a game of whack-a-mole but currently it's entirely unrestricted for pupils and that's not exactly the best...
