Reasons posts are deleted vary, but don't take it personally. Most commonly they are simply deleted because they are not real questions about how to hack your diet. Sometimes they are quite funny and interesting, but if they are not real questions, they don't belong here.
It's not appropriate to stalk the mods into other threads and ask them why your question was deleted.
I guess since there is no way to PM someone on PaleoHacks, you gotta get creative if you're curious. Anyway I agree with not taking it personally. I might 'question' things, but in general, I believe that however the mods run PaleoHacks is how they run it.
