Certain websites and individuals might offer discounted gold/diamonds. Don't be fooled - it's a scam.
Such practices request private login data (such as Apple ID, Google Play credentials, etc.) to access your game account.
WARNING:
- These vendors will gain access to your account and often hijack the account and try selling it to other players.
- If you release your private information/credentials to 3rd parties, you're permanently placing your game and financial/online security in a high-risk situation.
Consequences of misconduct: Purchasing gold or diamonds from 3rd party vendors can lead to revoked in-app currency and can even get your account permanently banned.
