Hello, I am the creator of FishNet. While I naturally cannot validate all of those using our software, I do recognize a number of them.

I can also toss in some re-assurance that this detection method is quite safe and reliable. If the FishNet files are present, it's safe to assume there is a FishNet installation in the project.

I can confirm that Cat Warfare is using Fish-Net, ID: 923370

Can you please confirm that when this goes live there would be a 'FishNet' filter here? https://steamdb.info/tech/

Thank you.
