I've added a bunch of mitigations but found that they're faking the referrer when subscribing to newsletters and not even going through the site anymore.
Captchas do solve it though!

Though I didn't mention it in the article, InboxReads has been also sending a consistent stream of quality subscribers my way -- much more so than other directories. Thanks!
