As far as I can tell the task force is focused primarily on people who are selling gil for real world money. Reporting people for botting is, I'm sure, helpful on some level, but this isn't what they're concerned with. Now, if the bot was underground or using some other exploit, you'd see action in a reasonable time frame. I reported someone for this at one point, and I stuck around in the area to see if anything happened. Eventually a GM contacted me, asked me more information about what was going on, and shortly thereafter the offender was no more. I watched them for 2 hours before they up and vanished. So they DO do something, just not to minor offenders like bot users.
