Dear Sir,
Recently I developed a robot that collects reported IP lists from more than 160 resources and then tries to categorize and normalize these lists. Some of these resources are highly reputed, and some of them are personal-lists. I summarize the result in the https://bgprep.info/report web app. this tiny app provides basic search and reporting functionality and a free, unlimited rest API for researching purpose. Besides this, I maintain my database of IP-Location and BGP AS-location.
Currently, the information is updated regularly every week, but I will try to decrease the update interval. I am very eager to hear your feedback about this app.
Please consider this information, and related data is entirely free and remains free in the future.

Best regards.
