Can you inbox the main Dr. Osh with legendary rank to confirm it the newbie Dr. Osh is his alt, if not, the newbie account deserves a negative tag to make it more clear that he is not related to the former.
The main user you're mean (Legendary) it seems like inactive for over 1.5 months since Oct 1st. Maybe he didn't know that a very similar account username was registered on 14/11/2022 and posted regularly for several days. But it seems 1 PM for Dr.Osh (Legendary) was enough to let him know.
In this case, your account is an imposter.
Imposter, seems right. People would think it was the same person if they never paid attention to the rank of the two accounts.
