Unsure if set-up correctly

Hi,

I’ve installed the plugin as I get a lot of nuisance registrations specifically from “@hotmails.com” addresses, however, I’ve followed the set-up tutorial detailed here:

https://www.wpbeginner.com/plugins/how-to-block-disposable-email-addresses-in-wordpress/

And I’m still getting these registrations, is there something incorrect in these instructions? As it suggests, I’ve taken the big list of spam domains and put it in the box, one per line. Should I be using commas? Or putting “@” at the front of each domain? I’m not sure.

I’m an Easy Digital Downloads user, but I don’t think that should be interfering, as I believe it uses the normal registration form/process.

Thanks in advance.
