In your opinion, which rule violation is the worst?

To me I think it has to be data mining. I think data mining is an insult to all the developers who worked tirelessly for the game. It affects everyone unfortunately and not just those who want spoilers. I think it outranks gil sellers imo

What ToS violation do you think is worse?

using parsers of any kind is datamining own and others data.
