Adding credits requires no evidence but removing credits does require evidence?
That seems entirely backwards, conductive to misinformation and how do you even prove a negative?
Like this right here https://www.imdb.com/title/tt12362246/?ref_=fn_al_tt_1 a work created by a delusional narcissist who claims to have worked with Rooster Teeth even though it's clearly all archive audio. Then there's a credit here https://www.imdb.com/title/tt1821404/fullcredits?ref_=tt_cl_sm which credits Turbo Duo mascot character Johnny Turbo (albeit with Jonathan misspelled as Johnathan) (looking further into it, I found equally dubious credits on GameFAQs which also calls the existence of the credited Gina Brandstetter into question (not helped by the fact that all of Gina's other credits are USA productions while Digimon World was made in Japan) as a non-existent character (there is no "TK" in Digimon World. Takeru "T.K." Takaishi is a character from Digimon Adventure which didn't exist yet) . When I tried to correct these mistakes (I didn't do this with Gina Brandstetter due to uncertainty), I was rejected, even in spite of pointing out that Johnny Turbo was credited in spite of being a fictional character, it all just spits in the face of common sense.
