Like I said in another post, I think they should put in the terms of service they could see what programs are running together with FFXIV, then gathering information of all program names that can interact with FFXIV, then analyze program behavior compared with programs that can do certain stuff.
Also, they should do something about these people who sell UwU weapons across data center, is it not obvious this is real money? I think doing this, RMT/third party program will suffer a lot.
