@otaviocc I see that your project is under MIT license. If they do not include the copyright notice with your name, report them for license infringement. If they do, there is unfortunately not much you can do about it, since MIT doesn't require documenting changes from the original source (including documenting whether there is an original source...)You may want to update your licence to Apache, LGPL or AGPL if you don't want that to happen again in the future, as those licenses require forks/clones to clearly document where they come from and what modifications have been done.My rule of thumb is that for libraries, I like to use MIT, but for applications, I use AGPL, as it also protects from unlicensed SaaS usage.
