Can i get banned for playing SPT?

As long as you follow the install instructions exactly there is 0% chance of being banned installing SPT.

Using SPT breaks the Terms of Service agreement you agreed to when creating your EFT account which allows them to terminate your account at any time.

Therefore, we strongly advise against informing BSG staff/moderators you use SPT or make public videos showing yourself playing SPT!

While the EFT launcher doesn't check for SPT (verified as of the 9th March 2023), we advise you not to have SPT server/launcher running when launching or playing live EFT.
