Hey,
I think chargebacks are what every host has to go throughnow and then.
YES WE HATE THEM!!
Unfortunatly when our site was up we were getting like one a month. We are still working on comming up with a better protection scheme. Our biggest problem is we offer instant account setup. I rrather not go into detail on all our measure we take to prevent frued and chargebacks.
How ever one of the things we were doing for a while is not accepting customers who used free e-mail accounts. So someone that entered their e-mail address as
123@yahoo.com into our orderform would not be allowed to acutally get a hosting account with us. unless they called our 800 number to setup an account. You will find not many fake orders will come to you through your 800 number.
We actually have hired a internet security expert when we moved into our own building and they guy helped us alot with not only security for our building and inhouse networks but he gave us a few pointers on how to prevent some chargebacks and stuff like that.
