I suggested back when all that RMT /tell crap was going on allowing us to make our own filters to block messages. This was never implemented, but it would have been helpful to block RMT spam. It is also useful to block offensive or such content, but even better, it can be st to block any shouts that DON'T contain certain words. So if all you want is Abyssea invites you block all shouts that don't contain Abyssea or Aby as an example.

Certainly, not everyone would use it, but the ones who really don't want to "listen" to all the useless, juvenile garbage being shouted in Port Jeuno would almost certainly use it extensively. And since you can't reach a GM with any speed to report offensive content, and there's enough of it that screenshots could fill a 1 TB HD in less than a week, filters are the only way to go... Unless SE wants to actually put GMs in the affected areas so the garbage shouts are headed off in a hurry.
