Well, xNetWham sold servers, but ran a large shoutcast station called xnradio. Unfortunately, someone from a rival station (we think) decided to send a 999999999999.99mb packet to one of our servers. Hence the server company charged corresponding to the bandwidth. That single event costed our owner 1500 dollars. This guy was crazy, he put some of our guys out for days from dos attacks. He would get G-lined and still come back. Basically, dont make any enemies and youll be fine, and talk to your server supplier. Also, talk to plantronics, they are really good about sponsoring events, servers, ect... as long as you arent doing anything illegal and are advertising for them. Have fun with it but be carefull.
