Away from the copy-paste-typo argument. The timeline of the last active of the old account, time of creation of the new account and the new post via the new account is something that can not be under looked. It appears as though OP logged into the other old account shortly before deciding to create a fresh accusation via the newly created account.

June 13, 2024, 11:17:22 PM Time of registration of New account (Yxuyovysis384)
June 13, 2024, 11:26:57 PM The time the old account as last online (drhouse99)
June 13, 2024, 11:56:49 PM The time this accusation was made

All this happened within 40 minutes. I believe in coincidences but this?

Maybe we will just have to wait for the investigation results from Duckdice, but there is probably more into this case.
