How many people do you need to dedicate to policing every Data Center/Realm/World/Zone/Instance in the game, 24 hours a day, 7 days a week, 365 days a year?

How much extra are you willing to pay in order to provide each and every one of those people with a salary commensurate with the responsibility, given the fact that American minimum wage is not an option?

How willing are you to be accused and/or stricken from the game because some automated system decided that the 14 hours you just spent working toward a higher rating in the Ishgard restoration project seemed out-of-line with 'normal people' in game?

Sure, it seems like an easy enough thing to implement without knowing anything about the coding or staffing levels required.

Would you be willing for SE to monitor all of the processes running on your computer while playing FFXIV if that was guaranteed to eliminate bots?

Complain and report. Realize that what you might consider 'bots' may actually be people with behaviours you consider bot-like, and the reason you still see the exact same user (really?) after 3 years may be that they are not, in fact, a bot?
