No one likes gold spamming. It's intrusive and annoying, and takes away from your enjoyment of a game. In Lord of the Rings Online, spam in the chat channels has been cracked down on in a big way recently, so the spammers have gone back to doing a lot more mail-based spam. A recent post on the official forums clued us in on what's next for the on-going battle in the spam wars.
Book 12 will include an option when viewing mail to "Report as Spam", greatly increasing the ease of reporting a character for the player, and getting the information back to Turbine much quicker than before. But the really big weapon here is a solution that should already be in place: "...and we now have the ability to delete all mail sent by a character, so some of it you'll never see at all before it's nuked."
The ball is in your court spammers.
