i just *cough* make sure their internet stays down for a few weeks. I had one charge backer charged back $70 and i lost $180 total from fees (multiple packages), we publicly defamed him. He will be back online in a few weeks. The community understands the risks associated with chargeback fraud. I find running a server nearly impossible without, ensuring people dont come onto the internet. Through server rivalry, and retaliating to attacks, and even black mail to get your donation money back. Just post their ip on your website; Absolutely no way of telling who did what after that.
