I had an item listed for auction and received a bid on it, however before the payment could go through, ebay removed the item (a ww2 german helmet) for violating their hateful items policy and deleted the listing. I have since been charged an insertion fee of $100.

This seems utterly ridiculous for me to be charged by ebay for an item that sold and they then removed before I could finalise the sale. 

Do I have reasonable grounds to not pay this fee? I understand the item was "sold" on their system but they were also the ones who removed it and blocked the sale..................
