Reusability, Ports, and Author's Returns

[aquaponiee]

Would this apply to Fsonic too? I have the walk animation in SRB2 the Past because it was used during 2.2 development as a placeholder for the updated sprites and at the time it was marked as reusable (old system), but some time after the frames were added, Reusability/open asset status was taken away.

the rule about not being able to remove tha reusability tag is pretty recent, it did not exist back then.
fsonic is not reusable so you cannot use the assets from it without prior consent
