Question about Trademarked phrases as keywords - BingAds

I'm searching and not having much luck ... Maybe I'm blind.
I'm also in a hurry to be honest. I don't expect people to do my work for me but if anyone knows off the top of their head ...
Is it okay to bid on trademarked keywords in BingAds? Take "facebook" for example.

I'd really like to add BingAds to my list of PPC networks but I'm not sure how they'll handle things like that.
I'm worried they'll wind up pulling my ads.

Just an update for if anyone else is wondering ...
Bing is strict on trademarks but only to an extent - they follow the laws.
For instance, you cannot promote for trademarked keywords in the USA BUT if you're targeting the same keyword in a country where our trademark laws do not apply, you're good to go.
Figured I'd share this for any other BingAds noobs out there such as myself.
