Most people are not crooked and won't be doing this. Probably 99% I would say. But do you ever think that you're writing and ideas are susceptible to people who look at them and mine for ideas if not outright copy them? They'd just log on, browse, and when they come across something cool, they would be like, "Hmmmm...that's good" and they would copy it or imitate because you're too obscure to matter and most likely not to get caught. Especially when you cannot control your posts and even then, I hear the posts don't disappear, but go through a secondary optional deletion by moderators.
