How should I make SE team to work to ban permanently these morons?

[Evind]

I have sent a long letter to customer service about RMT users, and they told me to ask it to GM.

So I am telling(actually complaining) to GM about them, and he keeps telling me to report to STF team.

And I wrote all the names of bot users and reported to STF team.

And nothing happened.

I think it is an irresponsible action as a famous game company, and it makes me feel that the SE teams are just neglecting bot users by earning money from them.

What's your opinion to SE teams to ban all those stupid bot users permanently from FFXI?
