Blacklist Monitor starts with bad news

Hey wpmudev team!

Hope you have a wonderful day ..

I'm handling the tech stuff for Today I turned on Defender's Blacklist monitor and got the "BLACKLISTED" screen of marketing death. So, I checked with Sucuri, all clean. After a while Defender's blacklist monitoring also turns to "Domain clean".

What is the technical reason why the plugin states "blacklisted" and about 15 minutes later "well, clean after all"? Please consider to proof the "blacklisted" state harder before sending it out to the customer and trigger double checks and counter action.

Best regards,
