This is not the case of multiple sources. IT's about bbana claiming to receive permission from authors, particularly Happy Donald.
She clearly wrote (and also someone else who defended her in discord) that she received permission from Happy Donald.
I can skip points 1 & 2. She just need to verify for Happy Donald by following instructions in point 3.
Here are screenshots from conversation with joeypark in Discord few weeks ago.
Regardless of that bbana refused to stop and continued copypasta spam.
She got caught again 2 weeks later with 2 posts (5 total by then).
