This drama again
None of us really cares if he profits from using authorized or unauthorized assets. None of us really cares if this game is porn/NSFW/questionable/whatever you want to call it. None of us really cares if imaginary characters involved in sexual acts are underage and if the material is illegal in whatever part of the world you're in. And none of us definitely doesn't care if this game is law-abiding under TOS of any platform. All of them, fake issues.
If you did care and were in fact a true supporter of any rule listed above, you should have freaked out a long long time ago and have taken actions (and to be a consistent person, you would have to do this to a shit load of other 18+ VN games out there as well), rather than playing the game and pirating it to help it spread this whole time.
Same goes for porn being a main material or not, simply another segue into legality issue regarding distributing (but if it's just about how everyone sees this game differently in terms of structure, theme and what is important, then by all means please continue)
So why are we talking about legality? (Illusion studio assets, underage adult content, distribution platform rules, porn or not porn, etc)
→"Since you're not on solid ground, it's fine that I do the same by pirating and you are in no position to say and do shit to me"
Why are we talking about his profit model?
→ "If he drowned me, he might drown the innocent others then himself as well. So he won't do anything stupid and he better not!"
Why are we talking about any of it now?
→ "OMG he actually took actions HOW DARE"
This is some people here, bearing the core concept of "I want free stuff without consequence and I want it now!", either trying to find bargaining chips to leverage the act of piracy or reasons to convince themselves that even dev has no right to tilt this strange balance.
If you are truly concerned about whether the files are safe to download or not, don't download CP or just simply wait for two weeks and get any material from itch.io there. People say the suspending is killing me but really it won't kill.
---The following is my half ass understanding about game files; please point out anything outright incorrect---
Doesn't leaked content have to come from someone with legit source? So that would mean if Sel really wants to brick your system he would need to pinpoint the leakers and
individually and purposefully provide a copy of malware-containing copy via the same downloading website that all other subscribers use. So unless this technicality can be easily figured out, otherwise I don't this malware is something people need to lose sleep about. It's not some sketchy crack files you use to overwrite something, it's the same script file that chronologically shouldn't be there.
---End---
If you truly despise dev because of his behaviors, don't support him or simply don't play the game. Let his issues get to him rather than us exerting ourselves to fuck him up solely because you can't pirate here anymore (unless you had been extremely offended by him before, in that case I am not in position to tell anyone not to be offended and/or to gauge their grudges). If you feel like teaching him a lesson this way, then what you are doing is not boycotting and you seriously need a hobby.
