Maybe a thread on the forums that gets updated daily. IE:
"11-10: 500 Bots banned, 200m illegal zeny confiscated"
"11-11: 2000 bots banned, 800m illegal zeny confiscated. Gottem."
etc.
Throw some pictures of them getting the hammer or something. idk. I remember a week or so ago I saw a picture one of the mods posted(?) that had all the bots one of the hunters captured from one map or something.
Pros:
Gives us hope and shows us that something IS being done.
Cons:
???
