Do you have such experience that when you login to your Diablo 3 account, multiple friend requests pop up. However, they are actually not friend request but information from gold site or advertisement. Community manager Vaeflare replied as follows:
Just like the botters you mentioned, we take reports concerning gold spam very seriously and are continuing to take steps to combat it. As long as you are taking the time to report and block these users, then you are helping us ensure that we’re aware of which players are attempting to abuse the friend request system so that we can investigate them and take action against them.
We’re always looking to improve your online experience, and that includes the reporting system. Thanks for taking the time to give us feedback!
