Special Task Force has nothing to do with development of ARR.

A reason why nothing happens sometimes is because people report for the wrong things. For example, reporting a botter for "hacking". They'll investigate for hacking and then see nothing of the sort is taking place and close the report.

Also, the action does not necessarily mean insta-perma-ban. They may have been caught botting and given a warning or a temp ban and then you'll see them running around later.
