I got false DMCAed on a mod a while back by someone I literally hired to do development and server hosting for me who then violated our contract and ran off with a month’s fees after shutting down the server. The code he tried to DMCA me over (which was made to my specifications at my request and adjusted by me) was written under a paid contract. So not only could I have gone after him for the false DMCA, I probably could have gotten a year of server fees out of him.
But like, why? He’s that kind of petty, certainly, but I can’t be bothered with that shit. It was a blip. We recoded his tiny little half-assed mod that was already 90% a pre-existing mechanic, reuploaded, and waited the couple of weeks to be able to get our original back up. Whatever.
I think most people who are targeted by false DMCAs just don’t feel like wasting their time in the court system over some petty (if malicious) inconvenience.
