Guild Wars 2

This is not a real suggestion, but this is a request. Dear arena.net in my last two hours I reported more than 50 bots in various maps (I’m trying to complete the exploration 100%) but I think it need a better system than simple report.

“Please do something because they are destroying this beautiful game.”

Thx

Hi all,
i need to know if there is a method to know if your in game mail as arrived to the receiver.
I ask this because today i dropped a rare item from a mob and I wanted to sell it at trade lion company.
The fee cost was 3,75 gold but i had only 37 silver, so i asked to my guild mate if he could give me that money for the transaction and i would give him back 4 gold after the sale.
Then i wrote a new mail with 4 golds attached and sent it to him but he told me that he didnt receive any mails from me.
How can i know if my guildmate told me a lie?

thx for help
