How do I provide evidence I was not in several productions?

A small fiction podcast I performed in was recently added to IMDB.

I did not have a profile on the site before, but my appearances were credited to someone of the same name, who has appeared in several adult titles in the past.

For reference this is the profile: https://www.imdb.com/name/nm6052782/?ref_=tt_cl_t_2

I submitted corrections asking for a second profile to be made for my credits, but they were denied as "unable to verify".

What sort of evidence do I need to provide that we are two separate people? 

I am not prominent in the industry and have little in the way of public presence.
