As you can see, I am not a premium member. Just because of that doesn't mean that I am not trustworthy with a trackable. If I, or many other non-premium members found a bug or coin, we would try to help it with its goal. You don't need to spend money on something to enjoy it or to want to be a part of its community. Anyways, some people just pay the 40 dollars for a year premium before they have even geocached. They may or may not be as trustworthy as not premium members. So I don't think that only putting bugs in premium caches will do anything but make some non-premiums enjoy caching less. (Just so you know, my low found total is because I started three days ago and haven't had a weekend to cache on)
