You can find additional dirt on this project not contained in the medium.com post by looking at his past posts in this thread (and other threads, for example you can see the thread he started to get help from the mods to prove that stackoverflow manipulated an image to try to make it look like Gleb was extorting him for money- a good example of why you should not believe a thing stackoverflow says: https://bitcointalk.org/index.php?topic=1813991.msg18070334#msg18070334 and you can also find all the previous scams he was successful in spotting prior to this one)
