roblox account help/question

for background information, every few years i contact roblox support to try and see if i can get one of my old roblox accounts back that i made as a kid. it is now that time where i am trying to regain access, but i remembered something the last time i tried to regain access to the account, hence my question: can roblox accounts have an email that is non existent attached to its account? a few years back when i was trying to get the account back they asked me to confirm the email attached to it buy giving me only parts of the email. the email they provided looked exactly like my fathers email (which would make sense) except instead of gmail.com at the end of the email it was “gmal.com”. I think i remember there being other typos in the email that i was provided with to guess which made me raise the question im asking. thanks for any help
