    It’s a list of places you can get free, disposable email addresses. Protonmail fits here. Now, why anybody would use this list for mail filtering is a whole different question. They’d be blocking some huge email providers.

        Yes, but some are more difficult to get. Personal domains cost money. Edu, gov, and most business emails are harder to get.

      Quite a few companies block free email addresses from filling out forms due to abuse. Happens all the time.

          Companies that engage in business to business services.

          Say you have a free demo of the product you’re selling, but you want to limit downloads to other legitimate businesses, because that’s your market.

          You gate it behind a form, and rig the form submission to reject free and ISP email addresses.

          So someone@microsoft.com - desirable and allowed. someone@aol.com or cox.net - not your market, block form submission.

          Happens ALL the time.
