You had some good advices to act against the scammers.

For the sake of your own project, the best thing would have been to change the name of your project. Problem is, I think, you already have a network under this name. So you have to inform your followers, first with a "bulletin" on all your social media that explain, shortly and clearly, the problem, and then, update them regularly with the actions you are taking against the scammers (the more actions you'll take, the more it will reinforce your credibility). And to reassure them, you also post regular updates on your own project.

This is a bad thing that happens to you, but it has brought you some unwanted followers. As the saying goes, there's no bad publicity. If those persons found the project presented by the scammers interesting, they might as well find yours interesting too. It is up to you to show your legitimity and win their trust.
