While the emphasis of this product is on identifying temporary emails used to avoid providing true identities during signups, and not so much on identifying compromised mailservers, it's doing a great job so far, blocking spammy bot-driven registration attempts.
'Super easy to set up. And if first 24 hours, caught 252 suspicious accounts (and upon review, all of those were indeed fake), as well as flagging 76 potentially-suspicious domain-names that many of those email accounts were being used "from". The ROI on that is less moderator work in a busy discussion community.
We still also use ProjectHoneyPot to catch compromised IPs and mailservers and usernames ... and that's catching several others that Checker didn't know because of being a different scope. They are working great in tandem with each other.
Had a question for Support, and they were quick to respond friendly and helpfully via in-app live-chat.

It’s great to hear Checker helped block over 250 fake signups in just 24 hours — that’s exactly the kind of impact we aim for. We're glad setup was smooth and support responsive.
While our main focus is on detecting temporary and suspicious email domains, we’re actively expanding our Risky IP detection system. This feature helps identify connections coming...
