Regarding r120785

Is there a reason these aliases were removed? They were added because of uploads on other platforms, where at least one of these uploads on Twitter even predates the YouTube upload: ^grende_mirade platform:twitter
I'm asking this question in earnest, since we would like to respectfully honor a request like this (separation of accounts) if necessary. However, it would still need to be documented in some way so that, in the scenario a future individual were to independently verify this information or so happen to make the connection themselves, it would (hopefully) not be added by such a user.
This could be an example of how to document this: https://safebooru.donmai.us/artists/364322
