Rado Zuska was first known as Risa Ludovic at William Higgins (tip @ Gostoso)

Rado Zuska was introduced by William Higgins in 2011.

He has over 20 scenes released and even had a bareback threesome and a wank party with his supposedly 2 brothers in real life.

William Higgins already hired Rado back in 2001 as Risa Ludovic.

Maybe, William Higgins did not recognize him when he came back after 10 years.
