If you mean SMS, I don’t think you can’t anymore.

I remember in a old(er) version it was enough to block (unknown) telephone numbers.
I would say check the FAQ.

Hi, unfortunately SMS blocking has become technically impossible for us since Android versions 4.4 and higher, and as more and more users have Android 5 and 6, we decided not to add this feature in the 2016 version of our application, thanks for understanding.
