He ain't Joking! By that I mean is that it is a valid religion. Now whether or not this guy is indeed a believer looking for a vocalist I have no idea, but since there are followers of this religion, its possible this is a serious advertisement....
Beliefs and practice of castration
The name "Skoptsy" is a plural of "skopets", an archaic word meaning "castrated one" in the Russian language.
As their title indicates, the main feature of the sect was castration. They believed that after the expulsion from the Garden of Eden, Adam and Eve had the halves of the forbidden fruit grafted onto their bodies forming testicles and breasts. Thus, the removal of these sexual organs restored the Skoptsy to the pristine state before the Original Sin.
There were two kinds of castration: the "lesser" and "greater seal" (i.e. partial and complete castration). For men, "lesser" castration was the removal of the testicles only, while "greater" castration was the removal of the penis as well. In this the Skoptsy maintained that they were fulfilling Christ's counsel of perfection in Matthew 19:12 and 18:8,9. The earliest records of female castrations date from 1815. Usually the breasts only were amputated, according to the 1911 encyclopedia. Other accounts suggest that the labia were also removed.
The Skoptsy also believed that a chief evil of the world is rooted in the lepost (bodily beauty, human sexuality, sex appeal, etc.) which prevents people from communicating with God. The way to perfection begins with the elimination of the cause followed by the liberation of soul. Castration ensured that all sins caused by lepost could not be committed.
