I don't get why this is so difficult for SE? Do they have zero tools to sort this?

Have several monitors in the GM office that shows the shouts of every world server, when they spot an RMT shout they just type the name into their account controls, click the ban button. It should be as simple as this and it should work as instantly as this.

There is no excuse for it to take so long and all these comments say "We're banning them asap!" "we're trying to get them at the filter level" is just a bunch of nonsense. No investigation is required, if someone is spamming in shout they sell gil, its a complete TOS violation, regardless of whether its someone trolling or not ban them anyway.
