somebody uses my email for their banking and subscription.

all his banking transactions and bills come to my mailbox.

this has been going on for many years.

this guy has the same name as me. i checked his profile in linkedin. i even tried to call him but no response.

could it be gmail problem? or this guy is just too lazy to put email address when signing up for anything?

this make sense also.

how can he register bank account email without verification?

probably he just register the email, but choose SMS for verification instead ?
the mailbox address is my first and last name. its a very simple address and i got it because i registered it since 2007.

i think mailbox is safe coz i changed password few times before.
