Presently my daily mailbox receives 7 - 8 offers to buy gold, despite numerous reports put in to Support.
It’s tiresome and getting a bit annoying to “report” and empty my mailbox every day.
Once you buy that first bit of gold, they all put you on their mailing list.
Even when you don’t buy gold, you get bombarded. I am now seeing mail come in where you no longer have the option to delete the mail. Because the spammers put in a copper for a COD, your only choice is reply or return…even when you hit report player, that darn thing keeps showing up in the mail. It should automatically delete when you report the mail
In my case … no gold has been purchased. Problem still remains. 
Yup, same here
