Do the questions about survival food belong here?
I've asked questions about how to quickly make snails edible: https://cooking.stackexchange.com/questions/24456/how-to-quickly-prepare-snails and it was migrated to Cooking SE. I don't think this is the proper site for such questions, since as for me they've could be eaten raw if it would be safe (but it isn't, because of parasites that need to be destroyed).
So, what is wrong with such questions, that they are marked off-topic and migrated?
