It's difficult being a merit source and bypassing good posts without being able to send merits out to them, but it's not much of a problem, you can simply keep an eye on the posts you would wish to merit, and when you get a refill of your Smerits, you can return to merit those posts, it doesn't matter how long it takes, it's actually worth the wait.

And if your Smerits finish rather too quickly as you're actually a very active member and merit source, which would mean you'll come across merit worthy posts very often, you can consider reducing the amount of Smerits you send to a particular post.
