MSN spidering without proper UA

Hi guys,

I'm not really sure if this is regular practice with MSN (Bing) or not. Since a few weeks back, they've been spidering my website without a proper User Agent (meaning their UA does NOT say anything about bingbot. It's just a regular browser UA). This happens from three different IP ranges. Yes, I've checked thoroughly and the IP rangers are registered under MSN.

I doubt this is manual review, since it doesn't look at all as normal human behavior.

Did they officially stop declaring their bots in User Agent strings?

There are some significant discussions on the stealth of the bots.
