Integration guide: Check is account already added by another user or not

Sometimes users can try to add the same account to your Nextpost. Let’s make a double account prevention for that situation.

Use Proxy Manager Module by Joe Cramer for advanced proxy management, a lot of powerful features and fixes for your Nextpost script. Proxy limitation, replacement, package allocation, bulk upload and more.

This is not a CoddingMatters mod!
