oh gawd. He would try to make money off this thing hopefully it's more of a donate option than a required option. Not too surprising since lots of cheat tools cost money but those are for games with thousands of players not hundreds. The audience is too small to make any real cash from this and to try to do so just looks foolish. Not too surprising though, he has been trying to make money off this outdated game for what 7 years? Time to grow up and maybe put those skills to use making real money, Broomy.
tl;dr Don't pay, there are other people working on making the same trainer for free.
