It's important to note that those are the rules that have been in effect. There's nothing new. Her post was just to make sure everyone was aware of them, so that there's no excuse when the warnings were implemented. Those are not new either, they just haven't been used for a while.
The single word/smilie rule was put into effect several years ago because some members were going through all the current threads and posting only smilies on each. So the entire list of most recent posts was just those smilie only posts.
So don't spam smilies on every thread or "bump" threads with the word "bump".
Other than that, I wouldn't worry. I think I was the only one even aware of or that has referenced that rule.
