You suggested information regarding fake degrees, did you not?

No, I did not.

In regard to 'mate' and its usage by Australians and for that matter Brits as well. I assumed I was speaking to English first language blokes. You sound like you are that; you seem clear and concise. Have you seen any Australian and British films? Have you had no contact with these two nationalities? 'Mate' is friendly, friendly nor unfriendly, or unfriendly, according to context and or intonation. It does not mean I want to mate with you. There seems to be a jumping on people for no reason.
