I reopened one match who never responded when they "thought we had potential." OK, I figured what the heck. Still no response. A few weeks later I closed her for good.

One of my matches reopened communication after I send a final response of, "I think if we had met, etc." Basically she told me off. I had to chuckle - OK, if that's the way you feel, fine, be that way. I don't need this.
