Warbrain, like it or not, some people are just here for the free software. There are some weeks when I don't have time to do the heist, so I just look for the code, too.
People that just get the codes aren't taking anything away from the developers. You doing the heists does exactly nothing for the people providing this software. The only way you can help them is to buy the bundle, software, or to just donate money.
Furthermore, as the OP isn't putting ads on that blog, he won't gain a dime from it. Also, he isn't posting the codes on a personal blog, so he isn't going to benefit indirectly from this either.
While I can sort of see what you mean about putting the codes in the forums on MH, it's sort of a pain to have to dig through ten or twenty pages of posts to find a code. Moreover, I would argue that he is actually helping out the developers and MH by attracting people to the site (and thus the bundle sale).
And, on a personal note, don't pull rank on people. It's sad and childish. Being one of the first people here or the one with the most posts doesn't make what you say more valid than what anyone else does.
