Makes no difference. If the aircraft registration is shady the operators are shady. It is the DUTY of every aviator to expose dangers to the flying public. The UN, individual national foreign service organizations, applicable relief agencies, as well as the media must be alerted before the probable disaster occurs.
If the operator is above board, they can publicly defend themselves.
BTW this is an aviation rumor network. Perfect forum for initiating such public information. Anonymity is understandable and acceptable IMO.
