I searched too long for this… Couldn't find.

All I can say the artist is probably either: 稗田束夷人
Or (less likely): さぼいっく

I extracted the text from >>14008 and got:

盗撮!! = Voyeurism !!
名門校割礼 = Prestigious school circumcision
作 = Work
稗田 = Hieda
束夷人 = Concubine
画 = Picture
さぼいっく = Crap

稗田束夷人 = Kazuto Hieda
さぼいっく = Sabo ikku (pronounced)
