Puzzled, I am, when Microsoft spams me, and they are pretty regular visitors. After all, Microsoft owns the Bing search engine, and I let Bing freely crawl my site. So why would they want to spam me, and do it so often, using multiple ways? inquiring minds want to know.
Usually I see Microsoft come in using a missing user agent, pretty stealthily, and as I want all visitors to be identifiable, I ban them. They change IPs and do this regularly. Then there are the tor exit servers owned by Microsoft. I suppose that having Tor exit servers is Ok, as they are used by everyone.
