How are we supposed to react to RMT shouts?

what we are supposed to do about these RMT shouts.

As I have said before, I think the following would be the best idea:

1. A keyword blocker
2. Extend the /blist capped limit beyond 100.

The issue is, as you have mentioned - They use keyboard smashed names, in the attempt to make it more difficult to report them. They also, delete and just make a new character, and then repeat.

The only viable way I think, is a keyword blocker.
The extended /blist option more for mind numbing political/troll yells.

The most saddest part of your screenshot though, is that there are no other yells, of any kind. The screenshot would be blank minus the RMT.
