look up mangago.zone (username) it usually shows like a comment or smth they make
Sadly I dont think there is a way to search for someones acc but if you keep an eye on the home page they might show up!! Or if you know this person and you're looking for their profile just ask them to copy the link of their home page to send to you.
Tell that person to comment on specific manga
Idk how to find peoples accounts? (//∇//)
