I have a website that has around 5k Bing visits every single day. Basically my most expensive user. Compared to Google with about 70 visits daily.
I randomly block their IPs, tried some stuff with robots.txt and even completely banned it in the past as I thought this must be something else. It would just show up with new IPs and proceed.
The few times I checked it looked like official IPs. If I knew how I would sue Microsoft. They have no business in scraping my website 3-5 times a day when they send me basically no traffic
Edit:// it's also not my only website where bing goes crazy. And it's not new, this is going on for several years now (so no AI scraping I guess)
