Firstly, there was an update on the 7th.
Secondly, kemono does not update anything themselves. To be more precise, subscribers publish access keys there and through these very access keys kemono receives all the content available to the subscriber.
Thirdly, as I said, it is impossible to get rid of pirated subscribers. They will be there anyway, to one degree or another.
PS: I don't particularly like those who merge keys on kemono, since such people don't give a damn about the author's works or they don't know how kemono works. A good example is Tonkatsu, who asked to wait at least a week before draining, but the pirates from kemono absolutely do not care about this.
