I apologize if that has been already mentioned but a quick search did not yield any useful results.

Would it be possible to get some sort of lvl1 spam filter?

I do have Spam Sentry on my toons but even those gold selling messages do get blocked they still get relayed to my main and due to the fact that the increase of those annoying gold spams is getting worse by the day it is driving me bananas.

I still find the whisper relay function really useful but I just wish I could block them by level.

Once again, if that has been alreay brought up - my apologies.
