Being banned on Buycraft means that you've broken buycraft and multiple servers' terms of service.
In result, Buycraft suspends you from their services and completely blocks you from the ability to buy packages from servers whose store platform is hosted on Tebex.
The usual reason for most Buycraft bans are due to multiple matters of chargebacking (Refunding a payment without the server's permission), which is against Buycraft and many of the Minecraft servers' terms of service.
While I do believe this is out of InvadedLands' control, I do advise you to contact Tebex support if you believe the above claim is false, explaining the situation you're in and if you're still unaware of the reasoning for your ban, I'd advise you to ask them to let you know about it.
