I personally have seen a massive increase in teh gold spam in my mailbox and zone chat since the free 5 day trial, as they are free accounts. Now i know this will only last for 5 days or so and then it will settle back down to the normal 1 or 2 mails a day. My idea for cryptic....
Is find the accounts that are spamming, from the multitude of people who have ignored them from zone chat and from mails and then backtrace the account to the account that issued the 5 free days and ban both of them... This would kill alot more gold sellers/farmers and would be a fantastic weapon in cryptics battle agaist these gold selling smeggers.
