I guess, but I still would prefer something separate. I'm not wanting to risk anything here.
I mean, that option makes it so that there is no way anyone will know that you own the game? Its also the only option available IF you purchase it from steam. The only chance of being "caught" is if someone is actively viewing your steam account when you purchse the game... which you can prevent by turning your entire steam account into private mode, purchase, hide the game, then make your steam account public again, while that game remains invisible. Might be a Itch release, idk. Itch witheld funds for a couple months so DEV might not trust itch anymore. Expect Dlsite to remain JP only (idk if it will or will not, but its probably safe to assume).
Other than that piracy is the only option, and well apparently thats been a mixed bag according to the forums. Ive not suffered any negatives other than annoyance from purchasing it, and it makes me wonder if that is the difference between my lucky sob never having any issues, and others who im assuming are pirating the copy (personally idc if someone does or doesnt. But this is the first time ive heard of pirates campaigning against a dev when i personally have not had those issues they are complaining about, every time it was brought up before this dev, i wasnt directly involved so i couldnt confirm jack S lol).
