So let's see. As an experiment I just reported a few extremely popular threads in the DPS forums for teaching new players how to play their class that link to YouTube videos with parsers and also include data from the parsers in the forum itself. Thus we'll see if "Square enforces it 100%." My thoughts are they don't and won't. Those posts will be on these forums long after I am gone. They tell us we're cheating and then look the other way. And that's wrong; just plain wrong. They need to pick a side and stick with it.
I can almost ensure you that those posts will not be removed. It is 100% illegal, and 0% enforced making unwitting cheaters of us all; those that use the programs and those that are in guilds or parties that use the programs.
