I also always do my first playthrough completely blind. I have a specific save for that, my canon playthrough. I choose as if I were in the story. Then I branch out from there doing LI-specific or alignment-specific playthroughs. Finally, I use the official walkthrough to pick up any scenes that I missed or if I want to redo parts of a playthrough to get the best content with a certain girl. I paid for both season 1 and the official walkthrough on steam, so I don't feel like I was cheating or ripping off the dev.
I never use porn game mods, but I don't have the visceral hatred for them that some people seem to have. If someone wants to use a mod, who cares? I don't see why a dev should get that bent out of shape about it. Once a game travels off into the ether of the internet, you can't control what happens to it, so why lose sleep over it? People are going to jack your code, your renders, your story ideas...and of course pirate it no matter how much you fight against it.
In DPC's case, if he just simply enjoys writing mod-killing code for fun, then I guess that's fine, but if he is doing it because he truly hates mods and thinks he can somehow discourage or put a stop them, well then

He must view it as a vandal coming in and throwing a bucket of blood red paint all over his Mona Lisa.
