The most valid reason I can agree with.
If this happens, there would be alot of drama in the meta board.
But the banned accounts are public. Information can easily be accessed by anyone from modlog, Loyce.club and bpip. Why isn't there any drama in meta yet?
If impersonation was such a serious thing here, then that means even inactive accounts would be much prone to this, but this is not even happening often and even when it does, the DT members can easily notice the impersonating account and tag it.
