Proof of mailbox fully spammed?

Hi,

I got this problem, i´m reciving empty mails from some one with no name attached...its that bad i cant even sent myself mail.

So i wrote a ticket with this complain, the GM answered back with; he needs a sceenshot...wtf?
Just go and check my mailbox, check the sender and ban him for abuse.

So my question why should i send a screenshot to this upload ******ed page(witch i dont understand how to ues anyways,
yeah i red you stupid instructions and still dont understand how to)

Is it that mutch to ask to check the mail and sender.
Cause in the time it took the GM to answer my ticket he could have easily check my valid complain.

So i´ll ask again why the screen shot ? its not like its a chat abuse or anything els

cheers.
