When I start to sell on a new account or an aged one. I always start with only one item until it sells and increase by one each time after. Never had eBay ask me to verify or call them still. This strategy might have nothing to do with it, as there are probably many potential reasons they remove listings.
This is the only conclusion that made sense to me though, maybe it's because you listed so many at once on a fresh selling account. No matter what the cost of the item in my opinion, you should start as slow as possible and gradually build to stay under the radar.
