In all fairness to mysite51 do you think it is wise as a host joombyte to publicly publish the ip and isp information of one of your customers?
and then publish their cpanel account usernames?

somehow i think you have just shown all future customers how slack you are about their privacy and how irresponsible you are with your customers private information.

you could have dealt with this in a much more positive way, other than proving you are not to be trusted with customers private information.

if see more you part company with a customer, their private information is still private no matter how angry you feel. that should still be respected.
