I know, the problem is the "In cooperation with"
How am I cooperating with the tracker any more than I am cooperating with, say, BitcoinStore.com, where my customers can also spend their bitcoins?
If a bank has an ATM on a street corner, then they provide withdrawal of money. The customer can then go on to use that money on whatever the customer wants. Ice cream for his children, or buying narcotics in a dark alley. The bank's responsibility ends when they have given the customer the money.
Now, if the bank wrote on their homepage, or had stickers on their ATM saying that they're facilitating payments to a street vendor of narcotics. For example it said on the ATM: "Two block down towards the park, the blue house, you get all the dope you need!"
Then customers would take offence, it would be in the papers, it would be on the news, the bank would have to say they're sorry, and remove the stickers and the advertisement on their webpage.
If a bank has a branch in a challenged neighborhood, they KNOW that a lot of the money that are deposited and that are withdrawn often are involved in criminal trade. Does that mean that the bank should shut down their branch ? Remove their ATM's ? No! But they're wise about it, they simple provide a service to people. Of course if someone comes into the bank with a large stash, and act all dopey and tell them: "Yo, I'm gonna stash this lot in ma account yo, my dealahs have done good on the street yo!". Then the branch would probably call security and police and have him escorted out.
So it's all about playing it smart. If you know that your technology or service can be used for something nefarious, do not go around advertising it, or make service agreements or official partnerships with providers of questionable goods.
Fimp, I've heard you're a standup guy, but perhaps you're a little bit naive. I don't know the details of all this, but if you announce you're working with a tracker, then you're putting A BIG TARGET on your forehead. And later, when you do presentations, or get interviews by a news paper, they will always ask about how you support piracy and so on. Just don't have any official ties to any of this, and shut down any customers that openly tell you that they're going to use bitcoins for illegal purposes.
Don't be blinded by your own desire to make a profit. It can come back to bite you seriously. Be smart, be safe.
Also, please change the title of this thread, as it's misleading.
