I like your logic. A membership is supposed to cover a family, although technically at one residence. But I'll go with what you suggested.

The web site was getting full about the time I told you about your membership. I have since done some things to save some space, and so we're doing fine now. 

I was going to turn off restrictions for members only at one time, and then someone had to go and advertise that membership got you access to exclusive sections of the website. So I had to do something to honor that.  Live and learn.
