Do you have purchased this script from bustabit or you are just using this script without notifying bustabit? Is this script available as open source now? 
I have heard that this script is copyright protected and no-one can use it without bustabit permission.

Likely they bought it from someone else. For sure bustabit does not sell their script or it is open sourced.
They might have found someone selling a script that was built to imitate bustabit, but generally I do not think it is the same.
Bustabit does not have patent over their game anyway, so I think anyone can just create their own crash game.
