Is there any detail in canon that factually debunks the FedoraFreak = Dad Crocker theory? Or is there only evidence for/against it but no confirmation?

Fedorafreak isn’t Dad Egbert. His user name is pipefan413.

EDIT: Sorry, I reread and saw that you said Crocker. Fedorafreak isn’t Dad Crocker because his username is also pipefan413.
