BUbiNG is a bot from law.di.unimi.it. This domain stands for the Laboratory for Web Algorithmics (LAW) of the (DI) University of Milano (UNIMI) in Italy (IT). The laboratory is using Java to develop several software systems, among which is BUbiNG: BUbiNG is the next-generation web crawler built upon the authors' experience with UbiCrawler and on the last ten years of research on the topic. BUbiNG is an open-source Java fully distributed crawler (no central coordination). This last bit is true, since the project can be downloaded using GitHub. Since this means that everyone can use BUbiNG, and the University does not have a page to show the collected results, it is not clear what is done with the data that is being collected when this crawler visits your domain.
The Internet of Bots has evaluated BUbiNG against 50 different checkpoints, of which 17 have been confirmed as being positive. These checkpoints evaluate the transparency and occurrence of a bot and don´t necessarily say something about its quality. The BotRank is calculated as [17*2=] 34%. The details of the bot and the BotRank can be seen below. For more information on how the BotRank is made, you can visit the page Botrank.
