On 20 May 1997 Sebastian Bleisch was sentenced to two-and-a-half years' detention by the regional court in Schwerin for having used adolescents who were still under 16 years old in the 60 or so pornographic films he had directed since 1990. He evaded conviction on more serious charges, however, after the defence showed that the boys had approached Bleisch willingly and no psychological harm had occurred.

I believe someone had also interviewed one of the boys who worked under him, now an adult, where he said that he considered Bleisch to be a friend and mentor. I'll see if I can find this interview.

Edit: Here's the interviews. I'm not sure if this is where I first saw them or not, but it should suffice to show that Mr. Bleisch had a good relationship with the boys with whom he worked. As this page notes towards the end:

The authors quote from the verdict that says that Bleisch "ruthlessly used the developing sexuality of these youths, their curiosity, disorientation and natural urge to assert themselves", then laconically note that "the abused call the abuser a good friend".

The mental gymnastics of the prosecution in order to hold onto their biases and ignore reality is as flimsy and pathetic as you might expect.
