Seems if I submit my sites to Bing, I get 1000 times the spammer accounts and emails than if I do not. That is one reason I not only stopped submitting my sites to Bing, but effectively block their spiders from even getting to my sites.
I trust Microsoft to an extent, but I will NEVER trust Bing and their so called privacy.
Search engine - their "video" search allows some videos to be played directly in the search results - which *could* allows some pornographic and/or adult videos to be played right on bing.com, not requiring users to go to the original host site. This could be a problem for children & is a potential opportunity to skirt some site-blockers. (I believe bing.com takes some steps to prevent this & good blockers should prevent the content, regardless of where it's being watched - but the potential is still there.)
