To be fair, this is a Japanese developer we're talking about, right? They have a history of adamant opposition to piracy despite the potential benefits like free advertising. The only Japanese dev I have ever seen not take a hard opposition stance is Illusion.I mean, there's a "demo" on his site, even though it's like version 0.0.11, not only does it only have half of the main quest and didn't even have a "guard" function.
And you do have a point,You must be registered to see the linksactually attracts more attention and encourage pirates to pay for them, likeYou must be registered to see the linksto humiliate them, yet still leave the game full playable despite being able to detect piracy.
And f95zone is often one of the source of pirates turned supporters, often with links to the creator and the store itself, encouraging people to support the developers if they have the money.
The ones you see encouraging or doing nothing are typicallly smaller western devs while the ones who fight it tooth and nail are typically smaller eastern devs and big companies who are allied with some sort of anti-piracy watchdog like The Entertainment Software Association, who protects Bethesda games.
