3 isn't many. Just don't post consecutively in the same thread within 24 hours. If you think of something new to say and your post is the last in a thread, simply edit the post to append your new thoughts to it (if its been less than 24 hours since posting).
Some sites like reddit, twitter, youtube etc are famous for becoming successful by overcontrolling members.
True, might as well add Facebook to that list. But this is one of the most loosely moderated sites I've ever had an account at. Just follow the basic rule I mentioned and you'll be fine.
