This reporting feature is intended to handle RMT that directly harass players through intrusive messaging. Mine-bots and level-bots and whatever do not directly impact you in any way, aside from a buzz of irritation when you see them. They may indirectly harass you by negatively affecting the economy, but by and large the RMT most people hate are the ones flooding their chat with stupid ads.
To be honest, though, I think the whole thing is a placebo to begin with. I firmly believe that SE ALREADY had ways to quickly identify and ban RMT spammers. It's probably not hard to pick out players broadcasting the same message to random players for hours at a time without ever changing zones. It's why you'd rarely see the same spam-bot longer than a day at most. All the reports players painstakingly filled out? Binned instantly, because the RMT Task Force already knew about the bots in question. I believe the report feature is purely there to comfort frustrated players who want to have the feeling that they're doing something to help, without having to go through the painful process of filling out a report. In short: SE gave us the feature because we asked, not because it in any way helps the problem.
RMT, being composed of countless independent businesses, have more manpower than ANY single business could possibly hope to match and still maintain a profit. They will always be able to field new spam-bots as fast as SE can take them down, no matter how fast SE takes them down. The only relief will be found on overpopulated servers like Gilgamesh or Balmung, for the simple fact that it's difficult to create new characters on those servers - and even there, the RMT will squirm through the cracks as quickly as they can manage.
