Like I said, look what happened the two time something like this tried to be implemented. Don't be like the last two devs, have a brain, for the love of god.
I'll quote myself, as it's what I said to trol: If multi billionaire company cannot stop piracy, it's not a small team that will.
What is going to happen is either: You won't care much about the verification, thus people will just crack the mod, or, you will care so much about it you will just mostly work on making the DRM "better and better" only for it to be cracked in 5 min yet again, which will then prevent you from working on what actually matter for everyone, hopefully for you too, the mod.
And like Ruby said, those kind of DRM create drama, which then create attention, which totally go against the whole idea of being
discreet about it.
Have a brain, don't do that, be discreet, maybe post the mod somewhere like this forum in a mod section where only people passing by will know, doesn't have to be here, there is other place, don't talk about it much, and don't be like trol and do a whole website for the mod, which, again is extremely stupid when the point was that people keep their mouth shut about it.
I really hope you will make the good decision, if you don't, then clearly this mod is as good as dead, and we will pretty much all move on, after all other games also have NSFW mods that will most likely still be better, Minecraft has potential, but it kept getting thrown in a grave by people having no intelligence whatsoever, and I don't even consider myself smart.
