Links to blogs in sigs?

Are they allowed? This post wasn’t clear, because point 1. states that only paid members (I am not) may have a sig (I do). Point 3. says that paid members may have a link. Since point 1. is untrue, is point 3. untrue as well?

I’ll ask about point 1 because that may simply be out of date. But this says you can’t link to your blog:

You’re not a paid member.

But a paid member can, right?
