Google's system for DMCA claims is completely automated, so unfortunately there are no "smarts" in place to smell out the trolls. Case in point, a random guy in China got my account permanently banned by filing fake claims against the donation version of Mupen64Plus AE I had on there a while back. Never once was able to talk to a real person at Google, and my counter claims and emails to developer support were completely ignored. My guess is they'd rather just wash their hands of the whole thing rather than hiring someone to actually look into these cases to make sure they aren't complete bogus.
BTW, Techworkz (the guy whose branch doesn't have ads in it) got another DMCA filed against his app he re-published, from the same Michael T. character. This time he actually received an email as well:
Maybe we'll have more luck communicating with him directly this time to figure out who he is and what terms of the GPL specifically he believes are being violated. I expect he is just a random vigilante who is taking advantage of Google's flawed system to follow a calling that he apparently feels is worth committing perjury over. Really irks me that people can get away with this BS.I am the lead committer of the Mupen64 project, based in Romania. Do not attempt to reupload the app as I will file a DMCA claim against it. I have successfully filed DMCA claims against all N64 Emulators on the Google Play market because they all violate my code license.
If too many of your apps get taken down, your Google account will be banned.
