Depends on whether you are trying to reduce the likelihood of people tracking you across instances (for example, if one account is for porn). If you just want duplicate accounts on which you’ll do the same things, I don’t see why it would be a problem to use the same name.
Are there any reasons for/against using the same username across different instances?
