I can confirm that these are legal and not some 'super secret special code' that users are trying to sell to other players.
You will not be banned for buying the 5th gens using these links. (After all, you donating to the site to get credits helps keep it alive)
Please also be aware that you use these links at your own risk as not all 5th gens are fully in the system yet.

Anyone caught selling these links saying they are secret codes to scam money out of users WILL be banned on sight.
It's still scamming and still a bannable offense. This is your only warning.
