Yes, Internet gambling is legitimate. If it wasn't, they would have no customers.
Yes, buying off-brand drugs from Chinese spam gangs is legitimate. If it weren't, they would have no customers.
Yes, helping Nigerian kings transfer money from one account to another is legitimate. If it weren't, they would have no gullible people to help them complete the transfer.
I say whatever we can do to disrupt the spam gangs and other types of gangs, the better. I have no sympathy for these onling gambling advocates. None.
