I do care too, but I think it was a pretty BAD move to ban every unactive member. I mean we had lots of member so this looked like an active site, but since there are only 7 registered users -_- that barely come here, then who would like to come and put their efforts into an unactive site? :/
My opinion though. Oh and you could try forumotion's advertising board, that helped to get members in my site and they will not ban you (if you don't advertise via pms and on every forum). Though you can ONLY advertise on your one, and only one thread, but believe me, it helps.
