In the 90's, if you had a porn site you couldn't take payments because no bank would touch adult sites. So some creative souls figured out that if they setup a "business" to sell "office supplies", the bank gave them their account, and people could use it to pay for porn. But every now and then someone would bid on one of the fake "items for sale", and have to be notified that it was "no longer available".
As a former havelock customer, I feel like one of the people who were bidding on the fake items. Sure you can make trades and see your rapidly decreasing balances, but whatever is going on in Panama with bitcoin currently, I cannot believe it has anything to do with the listings on Havelock.
