Show only comments only if published instead of created

Hello,

At this moment Activity has an option to show activities when a comment is created. I find that's a problem, since it doesn't filter if comments are moderated or not, and thus published or not. This is a real problem with spam robots, which try to send tones of coments which are not published due to the publication of comments policy but despite they are not published activity displays them.

Hope you can find a solution to this.
