I don't get how you all make a big deal about it. All kind of programs have flaws. It doesn't surprise me, that someone actually attempted to really get into modifieing Blockland.exe.
I'm imagining the endless fight between Badspot and the exploiters. (Not hacking. Hacking is a bit different from exploiting. However, the advantages you receive from it are the same, of course) And you can trust me, exploiters, hackers, or whatever will always find a way. And I mean the "serious" exploiters and hackers, not the trolls that pretend to have hacking tools. I'm actually talking about the real guys, who are really doing this. They will find a way, trust me. It doesn't matter how you patch something. They find a way. But of course, they will have to be creative in this case, as Blockland runs on a game engine, that uses a client-server architecture. If that wouldn't be the case, you could easily hack/exploit this game by just using your mind and some basic programming knowledge. But I'm happy, that's not the case.
Better you get evidence of the person exploiting or hacking, post it to Badspot and Badspot just revokes the key.
And again for those who still think that hacking a game or exploiting a game is impossible;
An old principle:
"Everything is dual, everything has two poles, and everything has its opposite. All manifested things have two sides, two aspects, or two poles. Everything "is" and "isn't" at the same time, all truths are but half truths and every truth is half false, there are two sides to everything, opposites are identical in nature, yet different in degree, extremes meet, and all paradoxes may be reconciled." - Kybalion.
