In case you receive STB blocked message and you are sure your Virtual MAC did NOT change, then it’s most likely that your Virtual MAC is used on app like STB EMU and this will cause a block.
We do NOT block anyone and have no way of knowing if you have an active Service with this Provider or not.
At the time of writing this it’s known that some major providers have their databases leaked, and this includes Virtual MAC’s.
For your safety we do NOT send or store any data beyond the Virtual MAC (and a randomnly generated serial number) to the Providers.
Thank you for understanding.
