These guys seem to be harvesting email addresses to use as return addresses on their spam. Many members of this board have been victimized by these spammers. If you are victimized you can expect hundreds of bounced messages from servers, you email blocked by spam filters, and your business reputation in the toilet.
Here is a link to a recent conviction:

Perhaps, we should go after these guys like we are going after the content pirates.
1. Charge them with identity theft.
2. Charge them with wire fraud.
3. Seek damages resulting from loss of email access and reputation.
Food for thought.
