I'm personally leery of punishing someone's relatives for their crimes; we have no way of knowing if they're even aware of what he's doing, let alone know that he's using their address as a location from which to commit his crimes.
While I agree that dragging them into any sort of proceedings against him might be a good way to have them make him stop, it'd be something different if, say, the federal government simply seizes their house (via civil or criminal forfeiture) as being the base of operations of a systemic copyright-infringement scheme (which is entirely possible; it's how we took down the Vampire Nation, after all).
Why not just send the cops to his house with a letter from the company alleging theft/fraud?
You don't have to be a lawyer to bring charges against someone. I had an assistant stealing $20 copays up front. I didn't get a lawyer. I called the cops. They handled it.
jh
If I was a lawyer (and I am most definitely not), I'd start off with a scary letter to his folks worded in a way that defines that we know who they are, who he is, and that they are colluding in an illegal operation with him and will thus be included in any legal actions if his entire operation does not cease and desist.
Basically a C&D letter, putting them in the cross-hairs of the oncoming storm if he doesn't stop. because they are named as the responsible party for his web-site. ICANN is serious about that domain registry requirement to name a person who is responsible (which is what WHOIS returns).
Based on the outcome of that, then you go feral on them all with any legal angle you can. Fact is, they raised a crap-son. If they don't correct it or disassociate from him, they deserve what's coming.
This ain't rocket science. 4chan retaliation is of the same scale of war. you pick a target, and hammer them with the tools of your trade.
I think the key issue is that those who have been most affected by his actions, at least of those I know, are not affiliated with 4chan in any way, nor are they the kind of people to even think of 4chan-level retaliation. That's not to say some of the artists he's wronged wouldn't be.....I can always hope.
Good idea, but for some reason business operations are out of the jurisdiction of cops.
Your assistant was local to you and the crime and the police.
I don't know that [MENTION=10738]camazotz[/MENTION] can call the police in Shipman's town and get them to go to his house.
Which is ironic, because online gamers can figure out where a rival lives and call a SWAT team in on them...
Well, you can always do some research on who he is, who to contact in his town and call the cops.
Just be prepared with URLs and proof that he is selling your stuff and that you want to press charges for theft.
It's a question of time/effort investment, and how one wants to resolve it. I personally would like to meet him in person and have him look me in the eye, and explain himself. At least I could understand if his behavior is sociopathic, caused by some sort of mental condition, or is purely driven by an amoral personality.
As I said, of the works he's stolen I am low on the list of offended parties --about four or five modules that he's ripped off, but which due to obscurity and being OOP weren't creating money for me previously-- so I could probably probably make a small claims court case against him for theft of copyrighted product, and seek reparations....which come to think of it might not be a bad idea if I feel like taking the time to do it. Other people, especially Ken St. Andre and others such as Fiery Dragon and Flying Buffalo Inc, have a significant case against him for unlawfully reproducing their product and selling it as his own.
Seems pretty cut and dried to me too. But until someone cobbles together enough scratch to sue the bastard and have enough stamina to win, he's not going to stop.
A guy broke into my house a few months back and stole some stuff. If I had that guy's name, I'd drop a load of trouble on him just on principal.
So whether you are a small fish or not, if you have proof of what you own, and that he has it and that's something the cops can bust him, I'd do it in a heartbeat. You can easily point out other victims to the cops, and they can do the legwork of contacting the other victims and confirming the violation to build up a heavier case.
