Using emulators (such as Bluestacks) is currently not against our Terms of Service, so you won’t get banned for using them. However, we cannot officially support them, so we recommend not using one. We can only offer support for Android and iOS device platforms.

We cannot offer support for multiple accounts as the game is designed to be played with only one account per person. We also cannot provide support for accounts lost due to trying to use multiple accounts. Please refer to our Terms of Service/Community Rules (2. Account Creation and Use; A): https://www.zynga.com/legal/terms-of-service

Please note that Game Center and Google Play only support one game per account. Trying to save multiple games to the same account will result in lost data.
