porn500.. are you saying it sounds to bizar to be true? If so, I agree with you, it is bizar. The proof is in the Zombaio stats, there is where I got it from and the proof is on the bank statements of those credit card holders, I've exchanged e-mails with two of them and they confirmed everything. I told them they should contact Visa about it. After all Tomas said it's not possible so that means the problem is not with Zombaio so everything's solved so no need to proof anything in here.
If you or anyone else still needs proof: compare the htpasswd file on your server with the htpasswd file generated by Zombaio reports / active members. If there are more accounts on the Zombaio generated file, look up those accounts that are on there but not on your server, then check the billing for those accounts in the Zombaio system. If this sounds too complicated for you, don't even bother, and continue pretending everything is fine
