Ah, in that case them being suspended is correct, and the system is working as intended. If you take a look at InfinityFree’s terms of service you’ll see that you’re only allowed to have three hosting accounts in total. Not per client area account, but only three ever. Period. By creating a second client area account to bypass that rule and create six hosting accounts, you have violated the terms of service. I suspect that either the system or a staff member at iFastNet noticed the issue based on your IP address.
The admin has pings disabled, but it doesn’t matter anyway because they can’t lift permanent suspensions. Your only hope is to open a ticket in the client area. The button to do so is accessible when an account is suspended.
I don’t know that they’ll reactivate all, if any of your suspended accounts. But if they refuse you can ask them to provide backups of the suspended accounts. They’ll usually be willing to do so.
