thats the thing its only bad if they try to claim credit for it. and even so, its not like its a big deal since you can build more stuff anyways. anyone stealing is only trailing behind you.
theres been so many super good builds made over the past 6 years but less than 1% have ever been released, and so a stuffton of effort has just disappeared to time. If anything, the fact that someone stole your build is proof that your building skills are impressive to others
