Besides that Pakistan is not a race but a country, the statement is about the users from Pakistan that are on Hive not the Pakistanis as a whole.
This statement is based on evidence as I have been fighting abuse around here since 5 years ago.

If you thought that the fraud on Hive is only limited to spam or unsourced images, then you know nothing about the amount of abuse on Hive.
The vast majority of fraud on Hive is content theft such as writing plagiarism.
Pakistani users specialise in plagiarism (writing & poems), identity theft (such as creating fake accounts pretending to be female), and creating botnets/groups of accounts to try to hit the newest curations or reward giveaways.
