I think that other dude was joking about the keyloggers, that's malware and if you're caught it's illegal. Not that anyone pursues that probably. If you really badly want this game off of F95 that would probably do it, it would be caught as malware, either stripped out on a release or likely removed from the site and the account banned that uploaded it.
A dev seriously wanting to put that in is a real bad red flag. I did play the release, it was obviously way too short for a yearly release and I had thought this game had been abandoned in all honesty until a few weeks ago, when I randomly checked. Most small devs like to use F95zone as advertisement and then take whatever patreons they get off that. After a few releases and if said dev is delivering, usually releases get delayed, but this is a pirate porn site so if there's any interest probably it will get leaked on here. If there's zero interest it won't get leaked but then that's its own issue.
With the issues this site has had recently more people will probably start sandboxing and blocking games off too, so if keyloggers and malware become that prevalent, they will be useless too. It won't stop piracy, it will just harm the devs, because patrons will question why they are getting spyware on their official downloads. And if they're not in the official download, that's what's going to get leaked, so a lose lose situation all around.
But you do whatever you want. This is just a friendly voice of reason. You've probably gotten more patreons off this website from the release leaked than you would have otherwise. If you don't want to take advantage of this site that's also on you, I make no judgment either way, but it seems kind of hard to get a game removed from on here.
Matt's GamesOFC I'm only joking, I like the f95 community.
While the situation sucks, no doubt, lets make and play games not bother with malware, but if you're curious this thread could be interesting for you:

If I where you I would focus more on, how to mitigate the damage the leak would do to your patreon supporters, maybe offer them an extra small additional scene at least?
