there's no real compensation for building anything in blockland aside from merit; badspot isn't paying Sylvanor to make seattle. and as someone who's had their stuff stolen before, it doesn't feel great. i spent a couple of weeks building that, and the only real pay i get for it is admiration, so when someone takes it as their own they get all that credit. i think it's silly to discount build stealing as something that just happens, cus no matter how innocuous it is it still feels a lil crappy.
that being said, you're only losing a tiny bit of admiration, and if you post your builds in the gallery a lot, you'll not only be more well known as the original builder but also the chances of your build being spotted and someone getting called out for it increase a lot. so it's a very minor issue, i think making scripts and such to protect your build is overkill. i always put a hidden part of the build that has a lil shrine with my name on it and some people who helped me, i think that's enough,
