Maybe this should be one of the reasons for you to cherish this forum than any other platform that may allow you to edit and change your identity for no reason, even if you got hacked or not they don't care, but do you remember that even for you to register on this forum, your email address was not verified the way other social medias do, this is bitcointalk, being moderated and has it own rules, it should not be equated with other random social media we often uses, anything you do here is attributed under your unique username, if you want a change of username, then you write to the admin.
